In enzymology, an inositol 3-alpha-galactosyltransferase () is an enzyme that catalyzes the chemical reaction :UDP-galactose + myo-inositol UDP + O-alpha-D-galactosyl-(1->3)-1D-myo-inositol 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. The systematic name of this enzyme class is UDP-galactose:myo-inositol 3-alpha-D-galactosyltransferase. Other names in common use include UDP-D-galactose:inositol galactosyltransferase, UDP-galactose:myo-inositol 1-alpha-D-galactosyltransferase, UDPgalactose:myo-inositol 1-alpha-D-galactosyltransferase, galactinol synthase, inositol 1-alpha-galactosyltransferase, and uridine diphosphogalactose-inositol galactosyltransferase. This enzyme participates in galactose metabolism. ==References== * 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「Inositol 3-alpha-galactosyltransferase」の詳細全文を読む スポンサード リンク
