FunctionInvolved in the biogenesis of the hydroxyphenyloxazoline-containing siderophore mycobactins. This peptide synthase forms amide bound between the carboxylic acid of salicylate and the alpha-amino group of serine (serine/threonine ligation).
ProductPhenyloxazoline synthase MbtB (phenyloxazoline synthetase)
CommentsRv2383c, (MTCY22H8.02), len: 1414 aa. MbtB, phenyloxazoline synthase (see citations below), similar to the N-terminal region of several synthetases e.g. Q9EWP5|SC4C2.17 putative non-ribosomal peptide synthase from Streptomyces coelicolor (2229 aa), FASTA scores: opt: 2878, E(): 4.1e-156, (46.85% identity in 1138 aa overlap); Q9Z399|IRP2 yersiniabactin biosynthetic from Yersinia pestis (2041 aa), FASTA scores: opt: 2297, E(): 5.3e-123, (38.55% identity in 1069 aa overlap); P48633|HMP2_YEREN|IRP2 high-molecular-weight protein 2 (may be involved in the nonribosomal synthesis of small peptides) from Yersinia enterocolitica (2035 aa), FASTA scores: opt: 2275, E(): 9.4e-122, (38.45% identity in 1069 aa overlap); O85739|PCHE|PA4226 dihydroaeruginoic acid synthetase from Pseudomonas aeruginosa (1438 aa) FASTA scores: opt: 2236, E(): 1.2e-119, (38.2% identity in 1330 aa overlap); Q9RFM8|PCHE pyochelin synthetase from Pseudomonas aeruginosa (1438 aa), FASTA scores: opt: 2229, E(): 3e-119, (38.0% identity in 1329 aa overlap); etc. Contains PS00455 Putative AMP-binding domain signature, and PS00012 Phosphopantetheine attachment site. Belongs to the ATP-dependent AMP-binding enzyme family.
Functional categoryLipid metabolism
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in M. tuberculosis H37Rv-infected guinea pig lungs at 30 and 90 days (See Kruh et al., 2010).
TranscriptomicsDNA microarrays indicate repression by iron and IdeR|Rv2711 in M. tuberculosis H37Rv (See Rodriguez et al., 2002).
MutantNon-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Slow growth mutant by Himar1-based transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
