Enzyme Information

2.4.1.18
1,4-alpha-glucan branching enzyme.
based on mapping to UniProt Q5SH28
Transfers a segment of a (1->4)-alpha-D-glucan chain to a primary hydroxy group in a similar glucan chain.
-!- Converts amylose into amylopectin. -!- The description (official name) requires a qualification depending on the product, glycogen or amylopectin, e.g. glycogen branching enzyme, amylopectin branching enzyme. -!- The latter has frequently been termed Q-enzyme.
