Tryptophan luminescence as a probe of enzyme conformation along the O-acetylserine sulfhydrylase reaction pathway.

Biochemistry - 25 Jun 1996

Strambini G B, Cioni P, Cook P F

Abstract excerpt

O-Acetylserine sulfhydrylase A (OASS-A) is a pyridoxal 5'-phosphate- (PLP-) dependent enzyme that catalyzes the last step in the synthesis of L-cysteine, the beta-replacement of acetate in O-acetyl-L-serine (OAS) by sulfide. The phosphorescence properties of the two tryptophans of wild-type OASS-...
