FEATURES

FAMILY

NAD(P)-dependent epimerase/dehydratase family

DESCRIPTION

Also known as UGE4_ARATH, UGE4, REB1, RHD1. Catalyzes the interconversion between UDP-glucose and UDP-galactose. Involved in channeling UDP-D-galactose (UDP-D-Gal) into cell wall polymers. Required for the galactosylation of xyloglucan (XyG) and type II arabinogalactan (AGII). Cooperates with UGE2 in cell wall carbohydrate biosynthesis and growth. homodimer. Heterodimer.
