Protein Domain : Sulphate/thiosulphate-binding, conserved site IPR000957

Type	Conserved_site
Description	Sulphate-binding protein (gene sbp or sbpA) and thiosulphate-binding protein (gene cysP) are two structurally related periplasmic bacterial proteins which specifically bind sulphate and thiosulphate and are involved in the transport systems for these nutrients [ , ]. There are two conserved regions in the protein, one located in the N-terminal region and the other in the central part of these proteins. The second region includes two adjacent amino acids (Ser-Gly) that, in sbp, are known to be essential for sulphate binding [ ].This entry represents a conserved site located in the N-terminal region of these proteins.
