ABSTRACT

Section II of this handbook is organized according to the classification of enzymes as presented in Enzyme Nomenclature (2). In this classification ‘‘hydrolases (EC group 3)’’ are listed separately from ‘‘transferases (EC group 2).’’ However, for several enzymes this distinction is not correct as they are transferases reacting with compounds with general formula R-OH in which R may also be H, (H-OH) as will be discussed below.
