EC 2.4.99.16     
Accepted name: starch synthase (maltosyl-transferring)
Reaction: α-maltose 1-phosphate + [(1→4)-α-D-glucosyl]n = phosphate + [(1→4)-α-D-glucosyl]n+2
Other name(s): α1,4-glucan:maltose-1-P maltosyltransferase; GMPMT
Systematic name: α-maltose 1-phosphate:(1→4)-α-D-glucan 4-α-D-maltosyltransferase
Comments: The enzyme from the bacterium Mycobacterium smegmatis is specific for maltose. It has no activity with α-D-glucose.
