Phosphoglyceromutase (PGM) from chicken breast muscle was titrated with p-mercuribenzoate (PMB), 5,5'-dithiobisnitrobenzoate (Nbs2), N-ethylmaleimide (NEM), iodoacetate and iodoacetamide. The effect of all of the sulfhydryl reagents, with the exception of NEM was to cause a loss in enzymatic activity. Addition of KCN following reaction with Nbs2 resulted in the recovery of a small amount of enzymatic activity. In the absence of substrate (3-phosphoglyceric acid) or cofactor (2,3-diphosphoglyceric acid) and in the presence or absence of 6 M guanidine hydrochloride, six sulfhydryl groups per mole of enzyme were titrated with PMB.
