4-α-d-glu·can·o·trans·fer·ase

(glū'kan-ō-trans'fĕr-ās),
Dextrin transglycosylase or glycosyltransferase; a 4-glycosyltransferase converting maltodextrins into amylose and glucose by transferring parts of 1,4-glucan chains to new 4-positions on glucose or other 1,4-glucans.

Tranferases (amylomaltase and cyclodextrin glycosyltranferase) target starch molecules at a, 1-4 glycoside linkages (Souza and Magalhaes, 2010).
The only related carbohydrate metabolising enzymes identified were amylase and amylomaltase, b- N-acetyl glucosaminyl transferase and a mannosyl transferase.
They found that another type of enzyme, a-1,4-a-1,4 glucosyltransferases (amylomaltase: Amase), is able to change the side-chain distribution of amylopectin.
