Gene Rv0780
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in de novo purine biosynthesis (at the seventh step) [catalytic activity: ATP + 1-(5-phosphoribosyl)-4-carboxy-5-aminoimidazole + L-aspartate = ADP + phosphate + 1-(5-phosphoribosyl)-4-(N-succino-carboxamide)-5-aminoimidazole]. |
| Product | Phosphoribosylaminoimidazole- succinocarboxamide synthase PurC (SAICAR synthetase) |
| Comments | Rv0780, (MTCY369.24), len: 297 aa. PurC, phosphoribosylaminoimidazole- succinocarboxamide synthase (see citations below), equivalent to MTU34957_1|PURC phosphoribosylaminoimidazole-succinocarboxamide synthase from Mycobacterium leprae (297 aa), FASTA scores: opt: 1986, E(): 0, (99.3% identity in 297 aa overlap). Also similar to others e.g. CAB56351.1|AL118514 phosphoribosylaminoimidazole-succinocarboxamide synthase from Streptomyces coelicolor (299 aa); etc. Contains PS01058 SAICAR synthetase signature 2. Belongs to the SAICAR synthetase 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). Translational start site supported by proteomics data (See de Souza et al., 2011) (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).
