UDP-galactose is the activated form of Gal, a crucial monosaccharide building block for human milk oligosaccharide (HMO). [2] The activated form of galactose (Gal) serves as a donor molecule involved in catalyzing the conversion of UDP-galactose to UDP-glucose. The conversion is a rate-limiting step essential to the pace of UDP-glucose ...
The systematic name of this enzyme class is UDP-galactose:sn-glycerol-3-phosphate 2-alpha-D-galactosyltransferase. Other names in common use include floridoside-phosphate synthase , UDP-galactose:sn-glycerol-3-phosphate-2-D-galactosyl transferase , FPS , UDP-galactose, sn-3-glycerol phosphate:1->2' galactosyltransferase , floridoside phosphate ...
The systematic name of this enzyme class is UDP-galactose:UDP-N-acetyl-D-glucosamine galactose phosphotransferase. Other names in common use include uridine diphosphogalactose-uridine diphosphoacetylglucosamine galactose-1-phosphotransferase , galactose-1-phosphotransferase , and galactosyl phosphotransferase .
The systematic name of this enzyme class is UDP-galactose:procollagen-5-hydroxy-L-lysine D-galactosyltransferase. Other names in common use include hydroxylysine galactosyltransferase, collagen galactosyltransferase, collagen hydroxylysyl galactosyltransferase, UDP galactose-collagen galactosyltransferase, uridine diphosphogalactose-collagen ...
The systematic name of this enzyme class is UDP-galactose:N-acetyllactosaminide 3-alpha-D-galactosyltransferase. Other names in common use include alpha ...
UDP consists of the pyrophosphate group, the pentose sugar ribose, and the nucleobase uracil. UDP is an important factor in glycogenesis . Before glucose can be stored as glycogen in the liver and muscles , the enzyme UDP-glucose pyrophosphorylase forms a UDP-glucose unit by combining glucose 1-phosphate with uridine triphosphate , cleaving a ...
Thus, the two substrates of this enzyme are UDP-galactose and myo-inositol, whereas its two products are UDP and [[O-alpha-D-galactosyl-(1->3)-1D-myo-inositol]]. This enzyme belongs to the family of glycosyltransferases , specifically the hexosyltransferases.
In enzymology, a glycoprotein-N-acetylgalactosamine 3-beta-galactosyltransferase (EC 2.4.1.122) is an enzyme that catalyzes the chemical reaction UDP-galactose + glycoprotein N-acetyl-D-galactosamine ⇌ {\displaystyle \rightleftharpoons } UDP + glycoprotein D-galactosyl-1,3-N-acetyl-D-galactosamine
