Gene Rv3383c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in biosynthesis of membrane ether-linked lipids. Catalyzes the trans-addition of the three molecules of IPP onto DMAPP to form geranylgeranyl pyrophosphate which is a precursor of the ether-linked lipids. Catalyze the consecutive condensation of homoallylic diphosphate of isopentenyl diphosphates (IPP, C5) with allylic diphosphates to synthesize prenyl diphosphates of various chain lengths. |
| Product | Possible polyprenyl synthetase IdsB (polyprenyl transferase) (polyprenyl diphosphate synthase) |
| Comments | Rv3383c, (MTV004.41c), len: 350 aa. Possible idsB, polyprenyl transferase (polyprenyl diphosphate synthase) , similar to many prenyltransferases involved in lipid biosynthesis e.g. Q9RGW1|GTR geranyl transferase from Streptomyces coelicolor (386 aa), FASTA scores: opt: 908, E(): 3.7e-50, (48.8/% identity in 334 aa overlap); Q9KWG0|GGDPS geranyl geranyl diphosphate synthase from Kitasatospora griseola (Streptomyces griseolosporeus) (348 aa), FASTA scores: opt: 801, E(): 2e-43, (41.5% identity in 347 aa overlap); Q9X7V8|SC6A5.12 putative polyprenyl synthetase from Streptomyces coelicolor (378 aa), FASTA scores: opt: 779, E(): 5.3e-42, (44.45% identity in 324 aa overlap); Q9S5E9 farnesyl, geranylgeranyl, geranylfarnesyl, hexaprenyl, heptaprenyl diphosphate synthase (self-HEPPS) from Synechococcus elongatus (324 aa), FASTA scores: opt: 563, E(): 2.3e-28, (39.85% identity in 241 aa overlap) (see citation below); O26156|IDSA_METTH|MTH50 bifunctional short chain isoprenyl diphosphate synthase [includes: farnesyl pyrophosphate synthetase (FPP synthetase) (dimethylallyltransferase) and geranyltranstransferase] from Methanobacterium thermoautotrophicum (325 aa), FASTA scores: opt: 540, E(): 6.5e-27, (35.75% identity in 319 aa overlap); P95999|GGPP_SULSO|GDS|GDS-1|SSO0061|C05010|C05_049 geranylgeranyl pyrophosphate synthetase (GGPP synthetase) (GGPS) [includes: dimethylallyltransferase and geranyltranstransferase and farnesyltranstransferase] from Sulfolobus solfataricus (332 aa), FASTA scores: opt: 511, E(): 4.5e-25 (36.9% identity in 244 aa overlap); etc. Also similar to Q50727|GGPP_MYCTU|Rv3398c|MT3506|MTCY78.30 probable multifunctional geranylgeranyl pyrophosphate synthetase [includes: dimethylallyltransferase; geranyltranstransferase; farnesyltranstransferase] from Mycobacterium tuberculosis (359 aa), FASTA scores: opt: 687, E(): 3.4e-36, (39.1% identity in 325 aa overlap). Contains PS00723 Polyprenyl synthetases signature 1. Belongs to the FPP/GGPP synthetases family. |
