1,4-α-d-glucan-branching enzyme
- 1,4-α-d-glucan-branching enzyme
Amylo-(1,4→1,6)-transglucosylase or transglucosidase; an
enzyme in
muscle and in plants (
Q enzyme) that cleaves α-1,4 linkages in
glycogen or
starch, transferring the fragments into α-1,6 linkages, creating branches in the
polysaccharide molecules; in plants, it converts
amylose to
amylopectin; this
enzyme is deficient in individuals with
glycogen storage disease type IV. SYN:
α-glucan-branching glycosyltransferase, amylo-1,4:1,6-glucantransferase,
amylo-(1,4→1,6)-transglucosidase, amylo-(1,4→1,6)-transglucosylase,
branching enzyme.
