Gene Rv0808
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in de novo purine biosynthesis (at the first step) [catalytic activity: 5-phospho-beta-D-ribosylamine + diphosphate + L-glutamate = L-glutamine + 5-phospho-alpha-D-ribose 1-diphosphate + H2O]. |
| Product | Amidophosphoribosyltransferase PurF (glutamine phosphoribosylpyrophosphate amidotransferase) (ATASE) (gpatase) |
| Comments | Rv0808, (MTCY07H7A.01c), len: 527 aa. PurF, amidophosphoribosyltransferase, equivalent to MLCB5_32|Q50028|PURF from Mycobacterium leprae (556 aa), FASTA scores: (91.3% identity in 518 aa overlap); and CAB96578.1|AJ278609 phosphoribosyl pyrophosphate amidotransferase from Mycobacterium smegmatis (511 aa)(see citation below). Also highly similar to others e.g. BAA89439.1|AB003158 amidophosphoribosyl transferase from Corynebacterium ammoniagenes (490 aa); P00497|PUR1_BACSU amidophosphoribosyltransferase precursor from Bacillus subtilis (476 aa), FASTA scores: opt: 1412, E(): 0, (46.2% identity in 470 aa overlap); etc. Contains PS00103 Purine/pyrimidine phosphoribosyl transferases signature. Belongs to the purine/pyrimidine phosphoribosyltransferase family. |
| 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). |
| Mutant | Non-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).
