Protein
5,5'-dehydrodivanillate O-demethylase oxygenase subunit
Organism
Sphingobium sp. (strain NBRC 103272 / SYK-6)
Function
Involved in the catabolism of 5,5'-dehydrodivanillate (DDVA), an intermediate in the biodegradation of lignin. Part of a three-component monooxygenase that catalyzes the O-demethylation of DDVA, leading to the formation of 2,2',3-trihydroxy-3'-methoxy-5,5'-dicarboxybiphenyl (OH-DDVA).
Similarity
Belongs to the bacterial ring-hydroxylating dioxygenase alpha subunit family.
