In enzymology, an amylosucrase () is an enzyme that catalyzes the chemical reaction :sucrose + (1,4-alpha-D-glucosyl)n D-fructose + (1,4-alpha-D-glucosyl)n+1 Thus, the two substrates of this enzyme are sucrose and (1,4-alpha-D-glucosyl)n, whereas its two products are D-fructose and (1,4-alpha-D-glucosyl)n+1. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name of this enzyme class is sucrose:1,4-alpha-D-glucan 4-alpha-D-glucosyltransferase. Other names in common use include sucrose-glucan glucosyltransferase, and sucrose-1,4-alpha-glucan glucosyltransferase. This enzyme participates in starch and sucrose metabolism. ==Structural studies== As of late 2007, 10 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , , , and . 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「Amylosucrase」の詳細全文を読む スポンサード リンク
