INTRODUCTION AMPSphere is a comprehensive catalog of antimicrobial peptides predicted using Macrel (DOI: 10.7717/peerj.10555) from 63,410 public metagenomes, ProGenomes v2.2 database (82,400 high-quality microbial genomes), and c.a. 4k non-whitelisted microbial genomes from NCBI. GENERATION Peptides were predicted using Macrel. Singleton peptides were removed, except those with a direct hit to the DRAMP database. Redundant peptides were hierarchically clustered using CD-HIT (version 4.6) at 100%, 85%, 75%, and 50% of amino acid identity (and 90% of overlap of the shorter peptide). The obtained clusters were sorted by decrescent size and numbered as families. Each level of clustering was called SPHERE and was used to understand the AMPs' structure accordingly to their orthology. Nucleotide sequences from the most frequent variants per AMP also were included in this version of AMPSphere. STATISTICS AMPSphere v.2021-03 contains 863,498 sequences (avg length: 36 amino acids, range 8-98). DRAMP database was used to find confirmed sequences with strict homology to reference. This approach showed that 2,488 peptides were previously confirmed in our dataset. IDENTIFIERS Peptides are named: >AMP10.XXX_XXX Where XXX_XXX is a unique numerical identifier (starting at zero). Numbers were assigned in order of increasing number of copies. So that the lower the number, the higher the number of copies of that peptide was present in the input data. Annotations were also provided as separated fields in the fasta file, containing their: - SPHERE families at level 4 (corresponding to hierarchically obtained clusters using 100%, 85%, and 75% of identity with a minimum overlap of 90% of the shorter gene). Example of the header: >AMP10.000_000 | SPHERE-III.001_396 VERSION This version v.2021-03 brings the validated SPHERE families. Using the families from level III, containing 8 sequences or more, we calculated the alignments and trees in Newick format, which were included in this version too. No major changes were made in the other files besides the naming.

Antimicrobial peptides (AMPs) have been recognized for their ability to target processes important for biofilm formation. Given the vast array of AMPs, identifying potential anti-biofilm candidates remains a significant challenge, and prompts the need for preliminary in silico investigations prior to extensive in vitro and in vivo studies. We have developed Biofilm-AMP (B-AMP), a curated 3D structural and functional repository of AMPs relevant to biofilm studies. In its current version, B-AMP contains predicted 3D structural models of 5544 AMPs (from the DRAMP database) developed using a suite of molecular modeling tools. The repository supports a user-friendly search, using source, name, DRAMP ID, and PepID (unique to B-AMP). Further, AMPs are annotated to existing biofilm literature, consisting of a vast library of over 10,000 articles, enhancing the functional capabilities of B-AMP. To provide an example of the usability of B-AMP, we use the sortase C biofilm target of the emerging pathogen Corynebacterium striatum as a case study. For this, 100 structural AMP models from B-AMP were subject to in silico protein-peptide molecular docking against the catalytic site residues of the C. striatum sortase C protein. Based on docking scores and interacting residues, we suggest a preference scale using which candidate AMPs could be taken up for further in silico, in vitro and in vivo testing. The 3D protein-peptide interaction models and preference scale are available in B-AMP. B-AMP is a comprehensive structural and functional repository of AMPs, and will serve as a starting point for future studies exploring AMPs for biofilm studies. B-AMP is freely available to the community at https://b-amp.karishmakaushiklab.com and will be regularly updated with AMP structures, interaction models with potential biofilm targets, and annotations to biofilm literature.

Type Analysis

The damp proofing service market is segmented into three main types: Chemical Damp Proofing, Physical Damp Proofing, and Integral Damp Proofing. Each type has distinct characteristics and applications, catering to varying needs and preferences of property owners and construction professionals. Chemical damp proofing involves the use of liquid chemical formulations that are injected into walls or applied as coatings to create a moisture barrier. This method is particularly effective for treating existing structures with rising damp issues, as it penetrates the masonry and forms a hydrophobic layer, preventing moisture from traveling through capillaries in the building material.

Physical damp proofing, on the other hand, relies on the installation of physical barriers such as damp proof courses (DPC) or membranes to obstruct the passage of moisture. This method is commonly used in new constructions where it can be seamlessly integrated into the building design. Physical damp proofing materials, such as polyethylene sheets or bitumen-based membranes, are placed at specific points in the walls or floors to block moisture ingress. This type of damp proofing is favored for its durability and effectiveness in providing long-term protection against moisture penetration.

Antimicrobial peptides (AMPs) are naturally produced by pro- and eukaryotes and are promising alternatives to antibiotics to fight multidrug-resistant microorganisms. However, despite thousands of AMP entries in respective databases, predictions about their structure–activity relationships are still limited. Similarly, common or dissimilar properties of AMPs that have evolved in different taxonomic groups are nearly unknown. We leveraged data entries for 10,987 peptides currently listed in the three antimicrobial peptide databases APD, DRAMP and DBAASP to aid structure–activity predictions. However, this number reduced to 3,828 AMPs that we could use for computational analyses, due to our stringent quality control criteria. The analysis uncovered a strong bias towards AMPs isolated from amphibians (1,391), whereas only 35 AMPs originate from fungi (0.9%), hindering evolutionary analyses on the origin and phylogenetic relationship of AMPs. The majority (62%) of the 3,828 AMPs consists of less than 40 amino acids but with a molecular weight higher than 2.5 kDa, has a net positive charge and shares a hydrophobic character. They are enriched in glycine, lysine and cysteine but are depleted in glutamate, aspartate and methionine when compared with a peptide set of the same size randomly selected from the UniProt database. The AMPs that deviate from this pattern (38%) can be found in different taxonomic groups, in particular in Gram-negative bacteria. Remarkably, the γ-core motif claimed so far as a unifying structural signature in cysteine-stabilised AMPs is absent in nearly 90% of the peptides, questioning its relevance as a prerequisite for antimicrobial activity. The disclosure of AMPs pattern and their variation in producing organism groups extends our knowledge of the structural diversity of AMPs and will assist future peptide screens in unexplored microorganisms. Structural design of peptide antibiotic drugs will benefit using natural AMPs as lead compounds. However, a reliable and statistically balanced database is missing which leads to a large knowledge gap in the AMP field. Thus, thorough evaluation of the available data, mitigation of biases and standardised experimental setups need to be implemented to leverage the full potential of AMPs for drug development programmes in the clinics and agriculture.

The total share of homes with damp problems in England's housing stock saw a general decrease between 2003 and 2022. In 2003, a total of 10.6 percent of homes that were inspected were found to have some form of damp problem. In 2022, this share had decreased to 4.1 percent. In that year, there were approximately 24 million houses in England.

In the 2 years to March 2023, an average of 4% of households in England had damp in at least one room of their home.

Plants interpret their immediate environment through perception of small molecules. Microbe-associated molecular patterns (MAMPs) such as flagellin and chitin are likely to be more abundant in the rhizosphere than plant-derived damage-associated molecular patterns (DAMPs). We investigated how the Arabidopsis thaliana root interprets MAMPs and DAMPs as danger signals. We monitored root development during exposure to increasing concentrations of the MAMPs flg22 and the chitin heptamer as well as of the DAMP AtPep1. The tissue-specific expression of defence-related genes in roots was analysed using a toolkit of promoter::YFPN lines reporting jasmonic acid (JA)-, salicylic acid (SA)-, ethylene (ET)- and reactive oxygen species (ROS)- dependent signalling. Finally, marker responses were analysed during invasion by the root pathogen Fusarium oxysporum. The DAMP AtPep1 triggered a stronger activation of the defence markers compared to flg22 and the chitin heptamer. In contrast to the tested MAMPs, AtPep1 induced SA- and JA-signalling markers in the root and caused a severe inhibition of root growth. Fungal attack resulted in a strong activation of defence genes in tissues close to the invading fungal hyphae. The results collectively suggest that AtPep1 presents a stronger danger signal to the Arabidopsis root than the MAMPs flg22 and chitin heptamer.
