Gene Rv3290c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Possibly involved in L-alpha-aminoadipic acid (L-AAA) biosynthesis. Catalyzes the transfer of the terminal amino group of L-lysine or L-ornithine to alpha-ketoglutarate [catalytic activity: L-lysine + 2-oxoglutarate = 2-aminoadipate 6-semialdehyde + L-glutamate]. |
| Product | Probable L-lysine-epsilon aminotransferase Lat (L-lysine aminotransferase) (lysine 6-aminotransferase) |
| Comments | Rv3290c, (MTCY71.30), len: 449 aa. Probable lat, lysine-epsilon aminotransferase, similar to Q05174|LAT_NOCLA from Nocardia lactamdurans (450 aa), FASTA scores: opt: 1702, E(): 1.1e-99, (60.35% identity in 439 aa overlap); and Q01767|Q53823|LAT_STRCL from Streptomyces clavuligerus (457 aa), FASTA scores: opt: 1676, E(): 4.9e-98, (60.15% identity in 434 aa overlap). Also some similarity to 4-aminobutyrate aminotransferase proteins (gamma-amino-N-butyrate transaminases). Belongs to class-III of pyridoxal-phosphate-dependent aminotransferases. Cofactor: pyridoxal phosphate. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified by mass spectrometry in whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate or membrane protein fraction (See de Souza et al., 2011). |
| Transcriptomics | mRNA identified by microarray analysis and up-regulated after 4h, 24h and 96h (highly) of starvation (see citation below). DNA microarrays show increased expression in M. tuberculosis H37Rv in BALB/c mice compared to SCID mice, after 21 days of infection (See Talaat et al., 2004). |
| 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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane 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 |
