G2IN77 · LIGXC_SPHSK

Function

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). LigXc probably functions as an intermediate electron transfer protein between LigXd and LigXa.
