Gene Rv3065 (emrE)
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in transport of multidrugs (tetraphenylphosphonium, erythromycin, ethidium bromide, acriflavine, safranin O, pyronin Y, etc) across the membrane (export): multidrugs resistance by an export mechanism (conferes resistance to toxic compounds by removing them for the cells). Responsible for the translocation of the substrate across the membrane. |
| Product | Multidrugs-transport integral membrane protein Mmr |
| Comments | Rv3065, (MT3150.1, MTCY22D7.17c), len: 107 aa. Mmr, integral membrane multidrugs resistance transporter (see citation below), equivalent to Q9CBP1|ML1756 probable multidrug resistance protein from Mycobacterium leprae (107 aa), FASTA scores: opt: 534, E(): 3.3e-28, (77.55% identity in 107 aa overlap). Also highly similar to bacterial proteins involved in resistance to ethidium bromide or methyl viologen e.g. O87866|QACG_STASP quaternary ammonium compound-resistance protein QACG (quarternary ammonium determinant G) from Staphylococcus sp. strain ST94 (107 aa), FASTA scores: opt: 307, E(): 1.8e-13, (39.8% identity in 103 aa overlap); P96460|QAC quaternary ammonium compounds resistance protein QAC from Staphylococcus aureus (107 aa), FASTA scores: opt: 304, E(): 2.8e-13, (40.4% identity in 104 aa overlap); Q57225|QACE_ECOLI quaternary ammonium compound-resistance protein QACE (quarternary ammonium determinant E) from Escherichia coli (110 aa), FASTA scores: opt: 300, E(): 5.2e-13, (48.15% identity in 108 aa overlap); AAG55967|Z1870 methylviologen resistance protein encoded within prophage CP-933X from Escherichia coli strain O157:H7 EDL933 (110 aa); P23895|EMRE|MVRC|EB|B0543 EMRE protein from Escherichia coli (110 aa), FASTA scores: opt: 290, E(): 2.3e-12, (43.55% identity in 101 aa overlap); etc. Also similar to the SugE protein of enteric bacteria. Belongs to the small multidrug resistance (SMR) protein family. Note that previously known as emrE. |
