Gene Rv3792
in Mycobacterium tuberculosis H37Rv
General annotation
| Type | CDS |
| Function | Involved in the biosynthesis of the mycobacterial cell wall arabinan |
| Product | Arabinofuranosyltransferase AftA |
| Comments | Rv3792, (MTCY13D12.26), len: 643 aa. aftA, arabinofuranosyltransferase (See Alderwick et al., 2006). Predicted to be in the GT-C superfamily of glycosyltransferases (See Liu and Mushegian, 2003). Probable conserved transmembrane protein, equivalent, but longer 21 aa, to Q9CDA6|ML0107 putative membrane protein from Mycobacterium leprae (632 aa), FASTA scores: opt: 1981, E(): 2.1e-110, (77.5% identity in 631 aa overlap). C-terminal end highly similar to C-terminus of O05765 putative product ORF 3 from Mycobacterium smegmatis (603 aa), FASTA scores: opt: 1261, E(): 1.4e-67, (70.7% identity in 266 aa overlap). A core mycobacterial gene; conserved in mycobacterial strains (See Marmiesse et al., 2004). |
| Functional category | Cell wall and cell processes |
| Proteomics | Identified in the cell membrane fraction of M. tuberculosis H37Rv using 2DLC/MS (See Mawuenyega 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). |
| Operon | Rv3790, Rv3791, Rv3792, and Rv3793 are co-transcribed, by Northern blot (See Goude et al., 2008). |
| 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).
