CC -!- FUNCTION: Maltosyltransferase that uses maltose 1-phosphate (M1P) as
CC the sugar donor to elongate linear or branched alpha-(1->4)-glucans. Is
CC involved in a branched alpha-glucan biosynthetic pathway from
CC trehalose, together with TreS, Mak and GlgB. {ECO:0000256|HAMAP-
CC Rule:MF_02124}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=[(1->4)-alpha-D-glucosyl](n) + alpha-maltose 1-phosphate =
CC [(1->4)-alpha-D-glucosyl](n+2) + phosphate; Xref=Rhea:RHEA:42692,
CC Rhea:RHEA-COMP:9584, Rhea:RHEA-COMP:10183, ChEBI:CHEBI:15444,
CC ChEBI:CHEBI:43474, ChEBI:CHEBI:63576; EC=2.4.99.16;
CC Evidence={ECO:0000256|ARBA:ARBA00000575, ECO:0000256|HAMAP-
CC Rule:MF_02124};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|ARBA:ARBA00011738, ECO:0000256|HAMAP-
CC Rule:MF_02124}.
CC -!- SIMILARITY: Belongs to the glycosyl hydrolase 13 family. GlgE
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_02124}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
