Gene Rv1086
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Catalyzes the first committed step in the synthesis of decaprenyl diphosphate, a molecule which has a central role in the biosynthesis of most features of the mycobacterial cell wall. Adds one isoprene unit to omega,E-geranyl diphosphate. The product, omega,E, Z-farnesyl diphosphate, is the putative substrate of Rv2361c product [catalytic activity: geranyl diphosphate + isopentenyl diphosphate = diphosphate + trans,trans-farnesyl diphosphate]. |
| Product | Short (C15) chain Z-isoprenyl diphosphate synthase (Z-FPP synthase) (Z-farnesyl diphosphate synthase) (Z-FPP synthetase) (Z-farnesyl diphosphate synthetase) (geranyltranstransferase) (farnesyl pyrophosphate synthetase) |
| Comments | Rv1086, (MTV017.39), len: 262 aa. Short (C15) chain Z-isoprenyl diphosphate synthase (see citations below), equivalent to NP_302598.1|NC_002677 possible undecaprenyl pyrophosphate synthetase from Mycobacterium leprae (262 aa), similar to many hypothetical proteins and several potential members of the upp synthase family e.g. NP_296167.1|NC_001263 undecaprenyl diphosphate synthase from Deinococcus radiodurans (339 aa); P20182|YT14_STRFR Hypothetical protein from Streptomyces fradiae (259 aa), FASTA scores: opt: 840, E(): 0, (51.0% identity in 259 aa overlap); and P38118|YARF_CORGL Hypothetical protein from Corynebacterium glutamicicum (234 aa), FASTA scores: opt: 729, E(): 0, (56.0% identity in 209 aa overlap); etc. Also similar to Rv2361c|MTCY27.19 (296 aa) (35.6% identity in 233 aa overlap). Contains PS01066 Uncharacterized protein family UPF0015 signature. Seems to belong to the UPP synthetase family. |
| Functional category | Cell wall and cell processes |
| 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 | 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). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
