The reaction catalyzed by a certain phosphatase enzyme is found to follow ping-pong kinetics and involves the transfer of a phosphate group from substrate A to substrate B.Which mode of catalysis is likely for this reaction?
A)Sequential catalysis.
B)Acid-base catalysis.
C)Transfer catalysis.
D)Covalent catalysis.

Question

Quizplus · Accepted Answer

Ping-pong kinetics often involves covalent catalysis, where the enzyme forms a temporary covalent intermediate with a substrate, facilitating the transfer of a group (like a phosphate) to another substrate.
