isomerase Biochem.|aɪˈsɒməreɪz, -s|
[f. isomer + -ase.]
Any enzyme which brings about an isomerization reaction; orig. applied to two particular enzymes (see quots. 1943, 1944).
1943I. Banga in Stud. Inst. Med. Chem. Univ. Szeged III. 67 When ADP had been incubated with isomerase, the product was split by actomyosin which suggested that isomerase had changed the molecular structure of ADP. It was for this reason that the name isomerase was given to the new protein. 1944Jrnl. Biol. Chem. CLVI. 109 Triose phosphate isomerase (or more briefly isomerase) is an enzyme..which catalyzes the reaction glyceraldehyde phosphate {equil} dihydroxyacetone phosphate. 1953Ibid. CCI. 83 Escherichia coli contains an adaptive isomerase catalyzing the equilibrium, d-arabinose {equil} d-ribulose. 1963C. H. Doering tr. Karlson's Introd. Mod. Biochem. ix. 173 Two enzyme systems are involved in the biosynthesis of uroporphyrin III from porphobilinogen: a deaminase and an isomerase. 1972J. R. Whitaker Princ. Enzymol. for Food Scientists xiv. 417 The ‘isomerases’ are enzymes which bring about an isomerization of the substrate. The name is formed on the order ‘substrate prefix-isomerase’. The prefix indicates the type of isomerization involved, e.g., ‘maleate cis-trans-isomerase’. |
