Enzyme Information

2.4.99.16

Starch synthase (maltosyl-transferring).

based on mapping to UniProt Q9L1K2

Alpha-maltose 1-phosphate + ((1->4)-alpha-D-glucosyl)(n) = phosphate + ((1->4)-alpha-D-glucosyl)(n+2).

-!- The enzyme from from the bacterium Mycobacterium smegmatis is specific for maltose. -!- It has no activity with alpha-D-glucose. -!- Formerly EC 2.4.1.n5.
