Gene Rv3377c
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Produces halimadienyl diphosphate (tuberculosinyl diphosphate) from geranylgeranyl diphosphate (GGPP) [catalytic activity: geranylgeranyl diphosphate = halima-5(6),13-DIEN-15-YL diphosphate] |
| Product | Halimadienyl diphosphate synthase |
| Comments | Rv3377c, (MTV004.35c), len: 501 aa. Halimadienyl diphosphate synthase; similarity with various proteins, notably cyclases involved in steroid biosynthesis in plants and bacteria e.g. BAB52679|MLR6369 from Rhizobium loti (Mesorhizobium loti) (516 aa), FASTA scores: opt: 533, E(): 5.6e-27, (30.45% identity in 522 aa overlap); Q9ZTN8 copalyl diphosphate synthase 1 from Cucurbita maxima (Pumpkin) (Winter squash) (823 aa), FASTA scores: opt: 484, E(): 1.2e-23, (28.35% identity in 388 aa overlap); Q38710|AC22 abietadiene cyclase from Abies grandis (868 aa), FASTA scores: opt: 382, E(): 5.2e-17, (25.55% identity in 462 aa overlap); Q41771|AN1 kaurene synthase a from Zea mays (Maize) (823 aa), FASTA scores: opt: 377, E(): 1.1e-16, (29.75% identity in 390 aa overlap); Q9AJE4 diterpene cyclase-1 from Kitasatospora griseola (Streptomyces griseolosporeus) (499 aa), FASTA scores: opt: 336, E(): 3.2e-14, (27.5% identity in 513 aa overlap); Q9SAU6 E-alpha-bisabolene synthase (fragment) from Abies grandis (782 aa), FASTA scores: opt: 317, E(): 7.8e-13, (25.25% identity in 479 aa overlap); etc. Note that this and the upstream ORF MTV004.36c have a significantly lower GC bias than the rest of the genome. This region is a possible MT-complex-specific genomic island (See Becq et al., 2007). Cofactor: Mg2+. |
| Functional category | Intermediary metabolism and respiration |
| Mutant | Non-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 and CDC1551 strains (see Sassetti et al., 2003 and Lamichhane et al., 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). M. tuberculosis CDC1551 transposon mutant fails to prevent phagosome maturation and acidification in bone marrow macrophages from BALB/c mice; mutant shows reduced survival in these macrophages (See Pethe et al., 2004). M. tuberculosis CDC1551 Rv3377c-Rv3378c mutant does not produce halimadienyl diphosphate or nosyberkol (See Mann et al., 2011). Check for mutants available at TARGET website |
