Gene Rv3432c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the production of GABA [catalytic activity: L-glutamate = 4-aminobutanoate + CO(2)]. |
| Product | Probable glutamate decarboxylase GadB |
| Comments | Rv3432c, (MTCY77.04c), len: 460 aa. Probable gadB, glutamate decarboxylase, similar to many e.g. P73043|gad|SLL1641 from Synechocystis sp. strain PCC 6803 (467 aa), FASTA scores: opt: 1684, E(): 6.2e-99, (55.35% identity in 457 aa overlap); Q9X8J5|SCE9.23 from Streptomyces coelicolor (475 aa), FASTA scores: opt: 1650, E(): 8.9e-97, (57.4% identity in 446 aa overlap); Q9AQU4|gad from Oryza sativa (Rice) (501 aa), FASTA scores: opt: 1498, E(): 3.7e-87, (51.6% identity in 432 aa overlap); Q07346|DCE_PETHY from Petunia hybrida (Petunia) (500 aa), FASTA scores: opt: 1485, E(): 2.5e-86, (51.15% identity in 437 aa overlap); etc. Belongs to group II decarboxylases (DDC, gad, HDC and TYRDC). |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | 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). |
| Mutant | Non-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 provides a growth advantage 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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
