Gene Rv0896
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in tricarboxylic acid cycle (KREBS cycle) [catalytic activity: citrate + CoA = acetyl-CoA + H2O + oxaloacetate]. |
| Product | Probable citrate synthase I GltA2 |
| Comments | Rv0896, (MTCY31.24), len: 431 aa. Probable gltA2, citrate synthase 1, highly similar to O33066|NP_302405.1|NC_002677 citrate synthase 1 from Mycobacterium leprae (431 aa), FASTA scores: E(): 0, (91.0 identity in 431 aa overlap); and AAF04133.1|AF191033_1|AF191033 citrate synthase from Mycobacterium smegmatis (441 aa). Also highly similar to others e.g. AAF14286.1|AF181118_1|AF181118 citrate synthase from Streptomyces coelicolor (429 aa); P42457|CISY_CORGL citrate synthase from Corynebacterium glutamicum (437 aa), FASTA scores: opt: 1847, E(): 0, (63.0% identity in 433 aa overlap); etc. Also similar to two other Mycobacterium tuberculosis citrate synthases, Rv0889|MTCY31.17c|citA (373 aa), FASTA score: (29.2% identity in 274 aa overlap) and Rv1131|MTCY22G8.20|gltA1 (393 aa). Contains PS00480 Citrate synthase signature. Belongs to the citrate synthase 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 in the cytosol and cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS (See Xiong et al., 2005). Identified in the aqueous phase of Triton X-114 extracts of M. tuberculosis H37Rv membranes using 1-DGE, 2-DGE, and MALDI-TOF-MS (See Sinha 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 culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See de Souza et al., 2011) (See Kelkar et al., 2011). |
| Mutant | Essential gene for in vitro growth of H37Rv in a MtbYM rich medium, by Himar1 transposon mutagenesis (see Minato et al. 2019). Disruption of this gene results in growth defect of H37Rv in vitro, by analysis of saturated Himar1 transposon libraries (see DeJesus et al. 2017). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
