Gene Rv3285
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in long-chain fatty acid synthesis (at the first step). Carries two functions: biotin carboxyl carrier protein and biotin carboxyltransferase [catalytic activity: ATP + biotin-carboxyl-carrier protein + CO(2) = ADP + orthophosphate + carboxybiotin-carboxyl-carrier protein]. |
| Product | Probable bifunctional protein acetyl-/propionyl-coenzyme A carboxylase (alpha chain) AccA3: biotin carboxylase + biotin carboxyl carrier protein (BCCP) |
| Comments | Rv3285, (MTCY71.25), len: 600 aa. Probable accA3, bifunctional protein acetyl-/propionyl-coenzyme A carboxylase, alpha chain (see citations below) equivalent to P46392|BCCA_MYCLE|BCCA|ML0726|B1308_C1_129 acetyl-/propionyl-coenzyme A carboxylase alpha chain from Mycobacterium leprae (598 aa), FASTA scores: opt: 3510, E(): 1.1e-196, (89.3% identity in 601 aa overlap). Also highly similar to other proteins e.g. P71122|ACCBC acyl coenzyme A carboxylase from Corynebacterium glutamicum (Brevibacterium flavum) (591 aa), FASTA scores: opt: 2776, E(): 5.6e-154, (71.95% identity in 592 aa overlap); Q54119|BCPA2 biotin carboxylase and biotin carboxyl carrier protein from Saccharopolyspora erythraea (Streptomyces erythraeus) (591 aa), FASTA scores: opt: 2723, E(): 6.7e-151, (70.5% identity in 590 aa overlap); Q54105|BCPA biotin carboxylase and biotin carboxyl carrier protein from Saccharopolyspora erythraea (Streptomyces erythraeus) (597 aa), FASTA scores: opt: 2721, E(): 8.9e-151, (70.05% identity in 594 aa overlap); Q9EWV4|2SCK31.20 putative acyl-CoA carboxylase complex a subunit from Streptomyces coelicolor (590 aa), FASTA scores: opt: 2626, E(): 2.9e-145, (68.25% identity in 595 aa overlap); etc. Contains PS00867 Carbamoyl-phosphate synthase subdomain signature 2, PS00188 Biotin-requiring enzymes attachment site. Similar to other biotin-dependent enzymes and carbamoyl-phosphate synthetases. AccA3 (Rv3285), AccD5 (Rv3280), AccD4 (Rv3799), and AccE5 (Rv3281) form a biotin-dependent acyl-CoA carboxylase in M. tuberculosis H37Rv (See Oh et al., 2006). |
| Functional category | Lipid metabolism |
| Proteomics | Identified by proteomics at the Statens Serum Institute (Denmark) (see Rosenkrands et al., 2000). Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). Identified in the cell membrane fraction 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). |
| 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).
