Metabolite Identification
Common NameLI-F05b
DescriptionLI-F05b is a metabolite belonging to the class of antimicrobial peptides (AMPs). Its chemical structure is characterized by a sequence of amino acids that confer its antimicrobial properties, allowing it to interact with bacterial membranes and disrupt their integrity. LI-F05b is part of a larger group of LI-F-type AMPs, which includes LI-F03a, LI-F03b, LI-F04a, and LI-F04b, all isolated from the bacterium Paenibacillus polymyxa JSA-9 (PMID:28650559 ). These peptides are involved in various biochemical pathways, particularly in the innate immune response, where they play a critical role in defending against microbial infections. The mechanisms of action often include the formation of pores in bacterial membranes, leading to cell lysis, as well as modulating immune responses by interacting with host cells. The study of LI-F05b and its related peptides contributes to the understanding of natural antimicrobial agents and their potential applications in developing new therapeutic strategies against resistant bacterial strains.
