Gene Rv2967c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in gluconeogenesis and lipogenesis. Pyruvate carboxylase catalyzes a 2-step reaction, involving the ATP-dependent carboxylation of the covalently attached biotin in the first step and the transfer of the carboxyl group to pyruvate in the second [catalytic activity: ATP + pyruvate + HCO(3)(-) = ADP + phosphate + oxaloacetate]. |
| Product | Probable pyruvate carboxylase Pca (pyruvic carboxylase) |
| Comments | Rv2967c, (MTCY349.20), len: 1127 aa. Probable pca, pyruvate carboxylase (ala-rich protein), equivalent to Q9F843|PYC pyruvate carboxylase from Mycobacterium smegmatis (1127 aa), FASTA scores: opt: 6232, E(): 0, (83.3% identity in 1127 aa overlap). Also highly similar to others e.g. Q9RK64|SCF11.26c pyruvate carboxylase from Streptomyces coelicolor (1124 aa), FASTA scores: opt: 5526, E(): 0, (74.65% identity in 1125 aa overlap); O54587|PYC pyruvate carboxylase from Corynebacterium glutamicum (Brevibacterium flavum) (1140 aa), FASTA scores: opt: 4811, E(): 0, (64.5% identity in 1132 aa overlap); Q9DDT1 pyruvate carboxylase from Brachydanio rerio (Zebrafish) (1180 aa), FASTA scores: opt: 3133, E(): 1.1e-171, (47.8% identity in 1142 aa overlap); etc. Contains PS00867 Carbamoyl-phosphate synthase subdomain signature 2, PS00165 Serine/threonine dehydratases pyridoxal-phosphate attachment site, and PS00188 Biotin-requiring enzymes attachment site. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell wall and cell membrane fractions 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 M. tuberculosis H37Rv-infected guinea pig lungs at 30 days but not 90 days (See Kruh 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). |
| 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). Essential gene by Himar1 transposon mutagenesis in H37Rv and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Check for mutants available at TARGET website |
