ClassAMP: Antimicrobial peptides (AMPs) are being explored as substitutes to antibiotics. The broad range of activity of AMPs, multiple cellular targets and their ability to inhibit multi-drug resistant microbes make them ideal candidates as future drugs. To explore AMPs as drugs it is essential to understand sequence-specificity relationship of AMPs. ClassAMP has been developed using Random Forests method to understand the role of sequence of AMPs in its specificity towards bacteria, fungii and viruses.
