01

Overview

Microcins are a class of low-molecular-weight, ribosomally synthesized antimicrobial peptides produced by certain Gram-negative bacteria. They exhibit potent antibacterial activity against closely related bacterial species through diverse mechanisms like membrane disruption, enzyme inhibition, and ROS generation. They are being explored as novel antimicrobials and microbiome modulators due to their stability and activity against antibiotic-resistant pathogens.
