Lens, mutarotase

With the establishment of the permease hypothesis, however, it was apparent that the mere formation of a complex with the mutarotase protein may be the necessary interaction in transport (15). The subsequent mutarotation could be considered to be a coincidental consequence of the complex formation. To support this idea, it was found that 1-deoxy glucose and a-methyl glucoside are excellent competitive inhibitors of the enzyme (16,61). Keston also showed that a number of cataractogenic sugars were inhibitors of lens mutarotase (62). It has since been shown that in all cases where a sugar is a substrate for the mammalian intestinal transport system it is also a competitive inhibitor of mutarotase.

Keston305-307 showed that the kidney, liver, and lens tissues of many animals contain an enzyme that catalyzes the mutarotation of a- and /3-D-glucose and other sugars it was called mutarotase.3 8,309 This, or a similar, enzyme had earlier been found in preparations of D-glucose oxidase from Penicillium notatum by Bentley and Neu-berger310 and Keilin and Hartree.309 The enzyme was extensively purified by Bentley and Bhate.140 The enzyme is also widely distributed in plant tissues.311...
