Abstract

Creatine kinase from rabbit muscle is inactivated by limited proteolysis with proteinase K from Tritirachium album. Gel-filtration and cross-linking studies showed that the limited proteolysis did not affect the molecular weight of the enzyme under non-denaturing conditions, but did cause changes in the reactivity of the reactive thiol group on each subunit and in the ability of the enzyme to form a 'transition-state analogue' complex in the presence of magnesium acetate plus ADP plus creatinine plus NaNO3.
