UniProtKB - A0A224AM54 (708G1_CITJP)
Protein
UDP-glycosyltransferase 708G1
Gene
UGT708G1
Organism
Citrus japonica (Kumquat) (Fortunella crassifolia)
Status
Functioni
UDP-glucose-dependent glucosyltransferase catalyzing the C-glucosylation of 2-hydroxyflavanones (2-hydroxynaringenin and 2-hydroxypinocembrin) and phloretin (PubMed:28370711).
No activity with flavanones, flavones or flavonols (PubMed:28370711).
Exhibits C-glucosylation activity toward 2-phenyl-2',4',6'-trihydroxyacetophenone (PubMed:28370711).
Can use UDP-xylose as sugar donor, but catalytic efficiency is much lower toward UDP-xylose than toward UDP-glucose (PubMed:28370711).
