General annotation
Gene namecysW
Rv numberRv2398c
FunctionInvolved in the active transport across the membrane of multiple sulfur-containing compounds, including sulfate and thiosulfate (import). Responsible for the translocation of the substrate across the membrane.
ProductProbable sulfate-transport integral membrane protein ABC transporter CysW
CommentsRv2398c, (MTCY253.23), len: 272 aa. Probable cysW, sulfate-transport integral membrane protein ABC transporter (see citations below), similar to others e.g. Q9K877|CYSW|BH3129 sulfate ABC transporter (permease) from Bacillus halodurans (287 aa), FASTA scores: opt: 765, E(): 4.1e-40, (43.8% identity in 249 aa overlap); P27370|CYSW_SYNP7 sulfate transport system (permease) protein from Synechococcus sp. strain PCC 7942 (Anacystis nidulans R2) (286 aa), FASTA scores: opt: 757, E(): 1.3e-39, (44.3% identity in 264 aa overlap); Q9I6K9|CYSW|PA0281 sulfate transport protein from Pseudomonas aeruginosa (289 aa), FASTA scores: opt: 753, E(): 2.3e-39, (44.4% identity in 250 aa overlap); P16702|P76534|CYSW_ECOLI sulfate transport system permease from Escherichia coli (291 aa), FASTA scores: opt: 633, E(): 5.7e-32, (38.2% identity in 267 aa overlap); etc. Contains PS00402 Binding-protein-dependent transport systems inner membrane component signature. Similarity with integral membrane components of other binding-protein-dependent transport systems and belongs to the CYSTW subfamily.
