Gene Rv1079
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in methionine biosynthesis: converts O-succinyl-L-homoserine to cystathionine [catalytic activity: O-succinyl-L-homoserine + L-cysteine = cystathionine + succinate (can also use hydrogen sulfide and methanethiol as substrates)]. |
| Product | Cystathionine gamma-synthase MetB (CGS) (O-succinylhomoserine [thiol]-lyase) |
| Comments | Rv1079, (MTV017.32), len: 388 aa. metB, cystathionine gamma-synthase (see citation below). P46807|METB_MYCLE cystathionine gamma-synthase from Mycobacterium leprae (388 aa), FASTA scores: opt: 2220, E(): 0, (87.3% identity in 387 aa overlap). Also similar to other Mycobacterium tuberculosis enzymes involved in methionine synthesis e.g. Rv0391 and Rv3340. Contains PS00868 Cys/Met metabolism enzymes pyridoxal-phosphate attachment site. Belongs to the trans-sulfuration enzymes family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). |
| Mutant | Non-essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Non-essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Non essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Required for survival in primary murine macrophages, by transposon site hybridization (TraSH) in H37Rv (See Rengarajan et al., 2005). Check for mutants available at TARGET website |
