Gene Rv0777
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in de novo purine biosynthesis (at the eight step) [catalytic activity: 1-(5-phosphoribosyl)-4-(N-succino-carboxamide) -5-aminoimidazole = fumarate + 5'-phosphoribosyl-5-amino-4-imidazolecarboxamide (also catalyzes: N6-(1,2-dicarboxyethyl)AMP = fumarate + AMP)]. |
| Product | Probable adenylosuccinate lyase PurB (adenylosuccinase) (ASL) (ASASE) |
| Comments | Rv0777, (MTCY369.21b), len: 472 aa. Probable purB, adenylosuccinate lyase, equivalent (but shorter 15 aa) to MLCB5.13|Z95151|g2076607|PURB adenylosuccinate lyase from Mycobacterium leprae (487 aa), FASTA scores: opt: 2640, E(): 0, (86.7% identity in 472 aa overlap). More similar to eukaryotic adenylosuccinate lyases than to prokaryotic adenylosuccinate lyases e.g. P54822|PUR8_MOUSE adenylosuccinate lyase from Mus musculus (484 aa), FASTA scores: opt: 762, E(): 0, (32.4% identity in 445 aa overlap); CAB99134.1|AL390188 putative adenylosuccino lyase (fragment) from Streptomyces coelicolor (362 aa); etc. Contains PS00163 Fumarate lyases signature. Belongs to the lyase 1 family, adenylossucinate lyase subfamily. |
| Functional category | Intermediary metabolism and respiration |
| Proteomics | Identified in the cell wall and cell membrane fractions of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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 for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
