| 4-alpha-glucanotransferase M-CSA #479 | Amylomaltase enzymes are structurally and mechanistically related to alpha amylases, although they almost exclusively catalyse trans-glycosylation reactions whereas alpha amylase enzymes catalyse hydrolysis reactions. The amylomaltase enzyme catalyses amylose disproportionation and the synthesis of large cyclic glucans, making these enzymes of interest to chemical and pharmaceutical industries. | EC: 2.4.1.25 (PDB Primary Data) |
