General annotation
| Type | CDS |
| Function | May form an ATP-driven O-antigen/lipopolysaccharide export apparatus, in association with RFBD|Rv3783. Responsible for energy coupling to the transport system. |
| Product | Probable O-antigen/lipopolysaccharide transport ATP-binding protein ABC transporter RfbE |
| Comments | Rv3781, (MTCY13D12.15), len: 273 aa. Probable rfbE, polysaccharide-transport ATP-binding protein ABC transporter, involved in O-antigen/lipopolysaccharides (LPS) transport (see Braibant et al., 2000), equivalent to Q9CDA0|ML0114 putative ABC transporter ATP-binding component from Mycobacterium leprae (272 aa), FASTA scores: opt: 1581, E(): 3e-83, (91.4% identity in 267 aa overlap). Also highly similar to AAK71283 LPS/O-antigen export permease from Coxiella burnetii (258 aa), FASTA scores: opt: 793, E(): 2.5e-38, (45.45% identity in 253 aa overlap); Q9PAF0|XF2568 ABC transporter ATP-binding protein from Xylella fastidiosa (246 aa), FASTA scores: opt: 758, E(): 2.4e-36, (47.75% identity in 243 aa overlap); Q56903|RFBE_YEREN O-antigen export system ATP-binding protein from Yersinia enterocolitica (239 aa) (see Zhang et al., 1993), FASTA scores: opt: 697, E(): 7e-33, (48.65% identity in 224 aa overlap); Q50863|RFBB_MYXXA O-antigen export system ATP-binding from Myxococcus xanthus (437 aa), FASTA scores: opt: 605, E(): 2e-27, (42.05% identity in 207 aa overlap); etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the ATP-binding transport protein family (ABC transporters). |

| Proteomics | Identified in the membrane fraction of M. tuberculosis H37Rv using 1D-SDS-PAGE and uLC-MS/MS (See Gu et al., 2003). 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). |
| 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). Required for growth in C57BL/6J mouse spleen, by transposon site hybridization (TraSH) in H37Rv (See Sassetti and Rubin, 2003). Essential gene for in vitro growth of H37Rv, by Himar1 transposon mutagenesis (See Griffin et al., 2011). Check for mutants available at TARGET website |
