Function
function
Maltosyltransferase that uses maltose 1-phosphate (M1P) as the sugar donor to elongate linear or branched alpha-(1->4)-glucans. Is involved in a branched alpha-glucan biosynthetic pathway from trehalose, together with TreS, Mak and GlgB.
Catalytic activity
- alpha-maltose 1-phosphate + [(1->4)-alpha-D-glucosyl](n) = [(1->4)-alpha-D-glucosyl](n+2) + phosphate
CHEBI:63576 + [(1→4)-α-D-glucosyl](n) RHEA-COMP:9584 = [(1→4)-α-D-glucosyl](n+2) RHEA-COMP:10183 + CHEBI:43474
