General annotation
Gene namecysA1
Rv numberRv2397c
FunctionInvolved in the active transport across the membrane of multiple sulfur-containing compounds, including sulfate and thiosulfate (import). Responsible for energy coupling to the transport system.
ProductSulfate-transport ATP-binding protein ABC transporter CysA1
CommentsRv2397c, (MTCY253.24), len: 351 aa. cysA1, sulfate-transport ATP-binding protein ABC transporter (see citations below), similar to other sulfate ABC transporter ATP-binding proteins e.g. P14788|CYSA_SYNP7 from Synechococcus sp. (344 aa), FASTA scores: opt: 1112, E(): 2.6e-56, (54.6% identity in 328 aa overlap); P74548|CYSA_SYNY3 from Synechocystis sp. (355 aa), FASTA scores: opt: 1063, E(): 1.7e-53, (51.9% identity in 343 aa overlap); Q9I6L0|CYSA|PA0280 from Pseudomonas aeruginosa (329 aa), FASTA scores: opt: 987, E(): 3.3e-49, (49.2% identity in 339 aa overlap); etc. Also similar to many ATP-binding proteins from Mycobacterium tuberculosis e.g. Rv2038c, Rv1238, Rv2832c, etc. Contains PS00017 ATP/GTP-binding site motif A (P-loop), and PS00211 ABC transporters family signature. Belongs to the ATP-binding transport protein family (ABC transporters). Note that previously known as cysA.
