| Type: | Family | Name: | Sulphur oxidation, SoxY |
| Description: | SoxY is encoded by one of the genes in the sulphur oxidizing gene cluster of alpha-proteobacteria. In the sulphur oxidation process, SoxY (which covalently binds sulphur) and SoxZ (which chelates sulphur) combine with each other to form the SoxYZ complex. The conserved cysteine residue in the sulphate-binding motif [(V/I)KV(T/S)(V/I)GGC] at the C terminus of SoxY is involved in forming a covalent S-S linkage with the sulphate ion to form SoxY-thiocysteine-S-sulphate, the first covalently bound sulphur adduct in sulphur anion oxidation by the proteins of the sox operon [, ].SoxY is a sulfate carrier protein with the GGCGG ir GGCG swinging arm C-terminal sequence. The Cys in the swinging arm is the residue to which the inorganic sulfate moiety becomes covalently attached. In some species, a closely related paralogue occurs as well (TIGR04487), with a swinging arm sequence AACIE. More distantly related forms have an additional C-terminal SoxZ-related domain. All members are periplasmic and have an N-terminal twin-arginine translocation (TAT) signal sequence []. | Short Name: | Sulphur_oxidation_SoxY |
