Gene Rv0973c (bccA)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | This protein carries two functions: biotin carboxyl carrier protein and biotin carboxyltransferase. Involved in the first step of long-chain fatty acid synthesis [catalytic activity: ATP + biotin-carboxyl-carrier protein + CO(2) = ADP + phosphate + carboxybiotin-carboxyl-carrier protein]. |
| Product | Probable acetyl-/propionyl-coenzyme A carboxylase alpha chain (alpha subunit) AccA2: biotin carboxylase + biotin carboxyl carrier protein (BCCP) |
| Comments | Rv0973c, (MTV044.01c, MTCY10D7.01), len: 667 aa. Probable accA2 (alternate gene name: bccA), acetyl-/propionyl-coenzyme A carboxylase (alpha subunit) [includes: biotin carboxylase ; biotin carboxyl carrier protein (BCCP)], highly similar to others e.g. CAB95892.1|AL359988 putative acetyl/propionyl CoA carboxylase alpha subunit from Streptomyces coelicolor (614 aa); NP_250702.1|NC_002516 probable acyl-CoA carboxylase alpha chain from Pseudomonas aeruginosa (655 aa); NP_420971.1|NC_002696 acetyl/propionyl-CoA carboxylase alpha subunit from Caulobacter crescentus ( 654 aa); NP_251581.1|NC_002516 probable biotin carboxylase/biotin carboxyl carrier protein from Pseudomonas aeruginosa (661 aa); etc. Also highly similar to others from Mycobacterium tuberculosis e.g. Rv2501c|P46401|MTCY07A7.07c|BCCA_MYCTU|ACCA1 probable acetyl-/propionyl-coenzyme A carboxylase alpha chain (alpha subunit) (654 aa), FASTA scores, opt: 250, E(): 4e-09, (28.6% identity in 182 aa overlap); and Rv3285|MTCY71.25|ACCA3 (600 aa); Z83018|MTCY349_20 (1127 aa), FASTA scores: opt: 838, E(): 0, (40.2% identity in 500 aa overlap). Contains PS00867 Carbamoyl-phosphate synthase subdomain signature 2 and PS00188 Biotin-requiring enzymes attachment site. |
| Functional category | Lipid metabolism |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). |
| Mutant | Non-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).
