Trypsin rapidly inactivated the catalytic activities of spinach ribulose bisphosphate carboxylase/oxygenase [3-phospho-D-glycerate carboxy-lyase (dimerizing), EC 4.1.1.39], but the stoichiometry of binding of the reaction-intermediate analogue carboxyarabinitol bisphosphate was only slightly reduced after proteolysis. Electrophoretic analysis indicated that several forms of the large subunit were generated during proteolysis but that the small subunit was resistant. Three tryptic peptides were… CONTINUE READING
