  • a The 13 enzymes assayed were nucleoside phosphorylase (NSP), three leucyl-leucyl-glycine peptidases (P3T, P3M, and P3B), alanine dehydrogenase (ALD), phosphoglucose isomerase (PGI), adenylate kinase (ADK), malic enzyme (ME), malate dehydrogenase (MDH), α-naphthyl-propionate esterase (EST), aconitase (ACO), indophenol oxidase (IPO), and catalase (CAT).
