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 RT erythropolis 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 CC and the transfer of a lysyl group from L-lysyl-tRNA(Lys) to CC membrane-bound phosphatidylglycerol (PG), which produces CC lysylphosphatidylglycerol (LPG), one of the components of the CC bacterial membrane with a positive net charge. LPG synthesis CC contributes to the resistance to cationic antimicrobial peptides CC (CAMPs) and likely protects M.tuberculosis against the CAMPs CC produced by competiting microorganisms (bacteriocins). In fact, CC the modification of anionic phosphatidylglycerol with positively CC charged L-lysine results in repulsion of the peptides (By CC similarity). CC -!- CATALYTIC ACTIVITY: ATP + L-lysine + tRNA(Lys) = AMP + diphosphate CC + L-lysyl-tRNA(Lys). CC -!- CATALYTIC ACTIVITY: L-lysyl-tRNA + phosphatidylglycerol = tRNA + CC 3-phosphatidyl-1'-(3'-O-L-lysyl)glycerol. CC -!- COFACTOR: Binds 3 magnesium ions per subunit (By similarity). CC -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein CC (Potential). CC -!- SIMILARITY: In the N-terminal section; belongs to the LPG CC synthetase family. CC -!- SIMILARITY: In the C-terminal section; belongs to the class-II CC aminoacyl-tRNA synthetase family. CC -!- SIMILARITY: Contains 1 OB DNA-binding domain.
