Gene Rv3708c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved at the second step in the common biosynthetic pathway leading from asp to the cell wall precursor MESO-diaminopimelate, to LYS, to met, to ILE and to THR [catalytic activity: L-aspartate-semialdehyde + orthophosphate + NADP(+) = L-aspartyl phosphate + NADPH]. |
| Product | Aspartate-semialdehyde dehydrogenase Asd (ASA dehydrogenase) (ASADH) (aspartic semialdehyde dehydrogenase) (L-aspartate-beta-semialdehyde dehydrogenase) |
| Comments | Rv3708c, (MTV025.056c), len: 345 aa. Asd, aspartate-semialdehyde dehydrogenase (see citation below), equivalent to many e.g. P47730|DHAS_MYCBO|ASD from Mycobacterium bovis (345 aa) FASTA scores: opt: 2150, E(): 1.6e-124, (97.7% identity in 345 aa overlap); or Q9JN40|ASD from Mycobacterium bovis (323 aa), FASTA scores: opt: 2021, E(): 1.2e-116, (97.5% identity in 323 aa overlap); Q9CB78|ASD|ML2322 from Mycobacterium leprae (351 aa), FASTA scores: opt: 1889, E(): 1.6e-108, (84.45% identity in 347 aa overlap); P41404|DHAS_MYCSM|ASD from Mycobacterium smegmatis (346 aa), FASTA scores: opt: 1801, E(): 3.9e-103, (80.3% identity in 345 aa overlap); etc. Contains PS01103 Aspartate-semialdehyde dehydrogenase signature. Belongs to the aspartate-semialdehyde dehydrogenase 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 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). Translational start site supported by proteomics data (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 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).
