[a. G. mutase (J. Parnas, at the suggestion of F. Hofmeister, in Biochem. Zeitschr. (1910) XXVIII. 284), f. L. mūt-āre to change: see -ase.]
a. Any enzyme which brings about a dismutation reaction.
1914[see dehydrase a]. 1943Sumner & Somers Chem. & Methods Enzymes xvii. 298 Aldehyde mutase brings about the Cannizzaro reaction. Here, two molecules of an aldehyde undergo an oxido-reduction.
b. Any enzyme which brings about the transfer of a phosphate group from one carbon atom to another in a molecule.
1938Jrnl. Biol. Chem. CXXIV. 552 Mannose-1-phosphate and galactose-1-phosphate, synthetically prepared, were not converted to the respective 6-esters by muscle, liver, or yeast mutase, with or without the addition of accelerating ions. 1964Cori & Brown in Florkin & Stotz Comprehensive Biochem. XV. vi. 212 In a system consisting of hexokinase, mutase and phosphorylase, glucose could be converted to glycogen, provided that the inorganic phosphate formed in the phosphorylase reaction was removed by barium ions. 1970R. W. McGilvery Biochemistry xv. 292 The sequence begins by a freely reversible mutase reaction, in which the phosphate group of glucose-6-phosphate is transferred to form glucose-1-phosphate. |
