CC -!- FUNCTION: Catalyzes the production of L-lysyl-tRNA(Lys)transfer and the
CC transfer of a lysyl group from L-lysyl-tRNA(Lys) to membrane-bound
CC phosphatidylglycerol (PG), which produces lysylphosphatidylglycerol
CC (LPG), one of the components of the bacterial membrane with a positive
CC net charge. LPG synthesis contributes to the resistance to cationic
CC antimicrobial peptides (CAMPs) and likely protects M.tuberculosis
CC against the CAMPs produced by competiting microorganisms
CC (bacteriocins). In fact, the modification of anionic
CC phosphatidylglycerol with positively charged L-lysine results in
CC repulsion of the peptides (By similarity). {ECO:0000250}.
