UDP-glucuronosyltransferase 3A1

Gene

UGT3A1

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at transcript leveli

Functioni

UDP-glucuronosyltransferases catalyze phase II biotransformation reactions in which lipophilic substrates are conjugated with glucuronic acid to increase water solubility and enhance excretion. They are of major importance in the conjugation and subsequent elimination of potentially toxic xenobiotics and endogenous compounds (By similarity).By similarity

Catalytic activityi

UDP-glucuronate + acceptor = UDP + acceptor beta-D-glucuronoside.
