title: [Polyfunctional enzymes].
abstract: The properties of enzymes possessing several autonomous functions distributed among the domains of the polypeptide chain are considered. Three types of such proteins have been characterized: (i) bifunctional enzymes catalyzing consecutive reactions of metabolism: (ii) enzymes capable of catalyzing different reactions that are not consecutive and, (iii) enzymes catalyzing oppositely directed reactions. Possible advantages of various reactions catalyzed by the same protein are discussed.
