Gene Rv2438c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in biosynthesis of NAD. Can use both glutamine or ammonia as a nitrogen source [catalytic activity: ATP + deamido-NAD(+) + L-glutamine + H(2)O = AMP + diphosphate + NAD(+) + L-glutamate]. |
| Product | Glutamine-dependent NAD(+) synthetase NadE (NAD(+) synthase [glutamine-hydrolysing]) |
| Comments | Rv2438c, (MT2513, MTCY428.08), len: 679 aa. NadE, glutamine-dependent NAD(+) synthetase (see citation below), equivalent to Q9CBZ6|NADE_MYCLE|ML1463 Glutamine-dependent NAD(+) synthetase from Mycobacterium leprae (680 aa), FASTA scores: opt: 3877, E(): 0. Also similar to others e.g. O83759|NADE_TREPA|TP0780 from Treponema pallidum (679 aa), FASTA scores: opt: 543, E(): 1.1e-25; O74940|NADE_SCHPO|SPCC553.02 from Schizosaccharomyces pombe (Fission yeast) (700 aa), FASTA scores: opt: 354, E(): 4.7e-14 ; P38795|NADE_YEAST|YHR074W from Saccharomyces cerevisiae (Baker's yeast) (714 aa), FASTA scores: opt: 339, E(): 4e-13; etc. Contains PS00591 Glycosyl hydrolases family 10 active site. Belongs to the NAD synthetase family in the C-terminal section. N-terminus shorter since first submission. |
| 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 cell wall and cell membrane fractions 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 by mass spectrometry in the culture filtrate and whole cell lysates of M. tuberculosis H37Rv but not the membrane protein fraction (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). 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 strain (see Sassetti et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011).
