CC   -!- FUNCTION: Catalyzes the ATP-dependent phosphorylation of maltose to
CC       maltose 1-phosphate. Is involved in a branched alpha-glucan
CC       biosynthetic pathway from trehalose, together with TreS, GlgE and GlgB
CC       (By similarity). {ECO:0000250}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=ATP + D-maltose = ADP + alpha-maltose 1-phosphate + H(+);
CC         Xref=Rhea:RHEA:31915, ChEBI:CHEBI:15378, ChEBI:CHEBI:17306,
CC         ChEBI:CHEBI:30616, ChEBI:CHEBI:63576, ChEBI:CHEBI:456216;
CC         EC=2.7.1.175;
CC   -!- PATHWAY: Glycan biosynthesis; glycogen biosynthesis.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the aminoglycoside phosphotransferase family.
CC       {ECO:0000305}.
