1.1.1.22	gallic acid	is a non-competitive inhibitor with respect to UDP-glucose and NAD+. It decreases specific activities of UGDH, but does not affect UGDH protein expression, thus UGDH activity is inhibited by polyphenols at the post-translational level. Gallic acid exerts strong antiproliferative activity in breast cancer cells. Heat inactivation of UGDH is accelerated to a greater degree by quercetin than by gallic acid. In the presence of gallic acid, the activity remaining after 30 min is 55% that of control	764

1.1.1.22	additional information	no substrate inhibition, K+ is not inhibitory up to 500 mM, not inhibitory: dimethyldicarbonate, EDTA	2	
1.1.1.22	additional information	in the presence of 0.12 mM 5-azido-UDP-glucose, 89% of the enzyme activity is lost after 5 min of photolabeling. When the enzyme is photolyzed in presence of 1 mM UDP-glucose, 11% of the enzyme activity is lost. 5-azido-UDP-glucose is photoinserting into a UDP-glucose-binding site on the human enzyme in a specific manner. Uracil, uridine, and glucose have a poor protective effect on the labeling, while UDP and UDP-glucose strongly inhibit photoinsertion	2
