TypeCDS
FunctionThought to be involved in active transport of drugs across the membrane (export): multidrugs resistance by an export mechanism. Responsible for energy coupling to the transport system and for the translocation of the substrate across the membrane.
ProductProbable drug-transport transmembrane ATP-binding protein ABC transporter BacA
CommentsRv1819c, (MTCY1A11.24), len: 639 aa. Probable bacA, drug-transport transmembrane ATP-binding protein ABC transporter (see citation below), equivalent to AL008609|MLCB1788.47 hypothetical ABC transporter from Mycobacterium leprae (638 aa), (74.9% identity in 634 aa overlap). Also similar to other transmembrane ATP-binding proteins e.g. Q57335|Y036_HAEIN hypothetical ABC transporter ATP-binding protein from Haemophilus influenzae (592 aa), FASTA scores: opt: 1235, E(): 2.8e-61, (40.8% identity in 623 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop), and PS00211 ABC transporters family signature. Belongs to the ATP-binding transport protein family (ABC transporters).
Functional categoryCell wall and cell processes
ProteomicsIdentified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega et al., 2005). Identified in the membrane fraction of M. tuberculosis H37Rv using nanoLC-MS/MS; predicted integral membrane protein (See Xiong et al., 2005). Identified by mass spectrometry in Triton X-114 extracts of M. tuberculosis H37Rv (See Malen et al., 2010). Identified by mass spectrometry in the membrane protein fraction and whole cell lysates of M. tuberculosis H37Rv but not the culture filtrate (See de Souza et al., 2011).
MutantNon-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). Non-essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Growth of M. tuberculosis H37Rv bacA|Rv1819c mutant in B6D2/F1 mice is comparable to wild-type, but mice infected with mutant survive longer; mutant is more resistant to bleomycin; no changes in mycolic acid and lipid content of the cell envelope were detected (See Domenech et al., 2009).
