PDP-Miner is an innovative AI/ML tool designed to detect prophage tail proteins with depolymerase domains across thousands of bacterial genomes. This tool is particularly relevant in the context of rising antibiotic resistance, which is projected to become a leading cause of human mortality by 2050. The study highlights the urgent need for alternative antimicrobial strategies, particularly those utilizing bacteriophages and their components.
The development of PDP-Miner involved creating a wrapper for an existing machine learning-based tool known as Depolymerase-Predictor (DePP). The workflow of PDP-Miner includes:
PDP-Miner successfully identified 10 high-confidence phage depolymerase gene candidates across 1,294 Pseudomonas genomes from the International Pseudomonas Consortium Database. The tool demonstrated high accuracy in identifying depolymerase domains, which are crucial for the infection process of bacteriophages.
Below is a Plotly graph illustrating the distribution of DePP scores among the identified candidates:
The findings from PDP-Miner suggest a promising avenue for discovering new antimicrobial agents derived from phage depolymerases. This approach could potentially mitigate the impact of antibiotic-resistant bacteria, particularly Pseudomonas aeruginosa, a significant human pathogen.
While PDP-Miner shows great promise, it is important to note that the accuracy of the predictions is contingent upon the quality of the training data used for the machine learning model. Future work should focus on experimental validation of the predicted proteins and expanding the tool's applicability to other bacterial species.
PDP-Miner represents a significant advancement in the field of bioinformatics, combining AI/ML with traditional genomic analysis to identify potential new targets for antimicrobial therapy.
