PROSITE documentation PDOC00337 [for PROSITE entry PS00757]Prokaryotic sulfate- and thiosulfate-binding proteins signatures
Sulfate-binding protein (gene sbp or sbpA) and thiosulfate-binding protein (gene cysP) are two structurally related periplasmic bacterial proteins which specifically bind sulfate and thiosulfate and are involved in the transport systems for these nutrients [1,2].
As signature patterns for these proteins we selected two conserved regions; one located in the N-terminal region and the other in the central part of these proteins. The second pattern includes two adjacent amino acids (Ser-Gly) that, in sbp, are known to be essential for sulfate binding [3].
