OC Bacteria; Actinobacteria; Corynebacteriales; Nocardiaceae; Rhodococcus. OX NCBI_TaxID=632772; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=B4; RA Takarada H., Sekine M., Hosoyama A., Yamada R., Fujisawa T., Omata S., RA Shimizu A., Tsukatani N., Tanikawa S., Fujita N., Harayama S.; RT "Comparison of the complete genome sequences of Rhodococcus erythropolis RT PR4 and Rhodococcus opacus B4."; RL Submitted (MAR-2009) to the EMBL/GenBank/DDBJ databases. 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}.
