In enzymology, a lipopolysaccharide 3-alpha-galactosyltransferase () is an enzyme that catalyzes the chemical reaction :UDP-galactose + lipopolysaccharide UDP + 3-alpha-D-galactosyl-(glucose ) Thus, the two substrates of this enzyme are UDP-galactose and lipopolysaccharide, whereas its two products are UDP and 3-alpha-D-galactosyl-[lipopolysaccharide glucose]. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP-galactose:lipopolysaccharide 3-alpha-D-galactosyltransferase. Other names in common use include UDP-galactose:lipopolysaccharide alpha,3-galactosyltransferase, UDP-galactose:polysaccharide galactosyltransferase, uridine diphosphate galactose:lipopolysaccharide, alpha-3-galactosyltransferase, uridine diphosphogalactose-lipopolysaccharide, and alpha,3-galactosyltransferase. This enzyme participates in lipopolysaccharide biosynthesis and glycan structures - biosynthesis 2. ==Structural studies== As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes PDB link 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lipopolysaccharide 3-alpha-galactosyltransferase」の詳細全文を読む スポンサード リンク
