FunctionSCNA_THITI Involved in the degradation of thiocyanate. Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedThiocyanate hydrolase (SCNase) is a member of a family of nitrile hydratase proteins, each of which contains a unique noncorrin cobalt center with two post-translationally modified cysteine ligands, cysteine-sulfenic acid or -sulfenate (Cys-SO(H)), and cysteine-sulfininate (Cys-SO(2)(-)), respectively. We have found that a partially matured recombinant SCNase was activated during storage. The crystal structures of SCNase before and after storage demonstrated that Cys-SO(2)(-) modification of gammaCys131 proceeded to completion prior to storage, while Cys-SO(H) modification of gammaCys133 occurred during storage. SCNase activity was suppressed when gammaCys133 was further oxidized to Cys-SO(2)(-). The correlation between the catalytic activity and the extent of the gammaCys133 modification indicates that the cysteine sulfenic acid modification of gammaCys133 is of primary importance in determining the activity of SCNase.
