1,4-alpha-d-glucan-branching enzyme 1,4-α-d-glu·can-branch·ing en·zyme (glū'kan-branch'ing en'zīm), Amylo-(1,4→1,6)-transglucosylase or transglucosidase; an enzyme in muscle and in plants (Q enzyme) that hydrolyzes 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 people with glycogen storage disease type IV. Synonym(s): α-glucan-branching glycosyltransferase, amylo-1, 4:1, 6-glucantransferase, amylo-, 4→1, 6)-transglucosidase, amylo-, 4→1, 6)-transglucosylase, branching enzyme1,4-α-d-glu·can-branch·ing en·zyme (glū'kan-branch'ing en'zīm) 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. |
