FLAVOPROTEIN STRUCTURE AND MECHANISM .8. STRUCTURE-FUNCTION RELATIONSFOR OLD YELLOW ENZYME

The past 5 years have seen tremendous progress in our know ledge of ol d yellow enzyme (OYE) as a number of OYEs have been cloned and express ed, a high-resolution crystal structure has been determined for one of these, and new substrates have been found that call he turned over by the enzyme. Together these studies do not yet define the physiologica l role of OYE, but they lead to significant new insights into the enzy matic properties and structure-function relations of OYE.
