Gene Rv1392
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the activated methyl cycle. Catalyzes the formation of S-adenosylmethionine from methionine and ATP. The overall synthetic reaction is composed of two sequential steps, AdoMet formation and the subsequent tripolyphosphate hydrolysis which occurs prior to release of AdoMet from the enzyme. [catalytic activity : ATP + L-methionine + H(2)O = phosphate + diphosphate + S-adenosyl-L-methionine] |
| Product | Probable S-adenosylmethionine synthetase MetK (mat) (AdoMet synthetase) (methionine adenosyltransferase) |
| Comments | Rv1392, (MTCY21B4.09), len: 403 aa. Probable metK, S-adenosylmethionine synthetase, similar to many e.g. METK_STAAU|P50307 Staphylococcus aureus (397 aa), FASTA scores: opt: 1484, E(): 0, (58.0% identity in 400 aa overlap). Contains PS00376 S-adenosylmethionine synthetase signature 1, PS00377 S-adenosylmethionine synthetase signature 2. Belongs to the adomet synthetase family. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | The product of this CDS corresponds to spot 1_264 identified by proteomics at the Max Planck Institute for Infection Biology, Berlin, Germany (see Mattow et al., 2001). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cytosol and cell wall fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and down-regulated after 96h of starvation (see Betts et al., 2002). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Essential gene for in vitro growth of H37Rv, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene by Himar1 transposon mutagenesis in H37Rv strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
