General annotation
Gene namecysT
Rv numberRv2399c
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 CysT
CommentsRv2399c, (MTCY253.22), len: 283 aa. Probable cysT, sulfate-transport integral membrane protein ABC transporter (see citations below), similar to others e.g. BAB48989|MLR1667 permease protein of sulfate ABC transporter from Rhizobium loti (283 aa), FASTA scores: opt: 756, E(): 7.9e-40, (40.95% identity in 271 aa overlap); Q9K878|cyst|BH3128 sulfate ABC transporter (permease) from Bacillus halodurans (279 aa), FASTA scores: opt: 750, E(): 1.8e-39, (44.55% identity in 258 aa overlap); P16701|CYST_ECOLI|CYSU|cyst|B2424 from Escherichia coli (277 aa), FASTA scores: opt: 669, E(): 1.9e-34, (40.0% identity in 260 aa overlap); etc. Contains PS00402 Binding-protein-dependent transport systems inner membrane component signature, and PS00017 ATP/GTP-binding site motif A (P-loop). Belongs to the CYSTW subfamily.
