STRUCTURE OF THE H61T MUTANT OF THE FLAVOENZYME VANILLYL-ALCOHOL OXIDASE IN THE APO FORM COMPLEXED BY ADP
Overview
Vanillyl-alcohol oxidase (VAO) is member of a newly recognized, flavoprotein family of structurally related oxidoreductases. The enzyme, contains a covalently linked FAD cofactor. To study the mechanism of, flavinylation we have created a design point mutation (His-61 --> Thr). In, the mutant enzyme the covalent His-C8alpha-flavin linkage is not formed, while the enzyme is still able to bind FAD and perform catalysis. The H61T, mutant displays a similar affinity for FAD and ADP (K(d) = 1.8 and 2.1, microm, respectively) but does not interact with FMN. H61T is about, 10-fold less active with 4-(methoxymethyl)phenol) (k(cat) = 0.24 s(-)(1), K(m) = 40 microm) than the wild-type enzyme. The crystal structures of, both the holo and apo form of H61T are highly similar to the structure of, ... [(full description)]
