Gene Rv1878
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in glutamine biosynthesis [catalytic activity: ATP + L-glutamate + NH(3) = ADP + glutamine + orthophosphate]. |
| Product | Probable glutamine synthetase GlnA3 (glutamine synthase) (GS-I) |
| Comments | Rv1878, (MTCY180.40c), len: 450 aa. Probable glnA3, glutamine synthetase class I, similar to many e.g. GLNA_BACCE|P19064 from Bacillus cereus (443 aa), FASTA results: opt: 497, E(): 5.2e-23, (29.0% identity in 331 aa overlap); etc. Also similar to C-terminus of FLUG_EMENI|P38094 flug protein from emericella nidulans (865 aa), FASTA scores: opt: 227, E (): 6.4e-13, (29.9% identity in 394 aa overlap). Note that the downstream ORF MTCY180.39c is similar to the N-terminus. Also similar to three other potential glutamine synthases in M. tuberculosis: Q10378|GLN2_MYCTU|GLNA2|Rv2222c|MT2280|MTCY190.33c|MTCY427.03c; Rv2860c|MTV003.06c|glnA4 and Rv2220|glnA1. Belongs to the glutamine synthetase family. |
| 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 M. tuberculosis H37Rv-infected guinea pig lungs at 90 days but not 30 days (See Kruh et al., 2010). Identified by mass spectrometry in the culture filtrate, membrane protein fraction, and whole cell lysates of M. tuberculosis H37Rv (See de Souza et al., 2011). Translational start site supported by proteomics data (See Kelkar 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). 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). Found to be deleted (partially or completely) in one or more clinical isolates (See Tsolaki et al., 2004). Check for mutants available at TARGET website |
