| 2.4.1.25 | maltononaose + maltotriose = maltoundecaose + D-glucose |
reaction mechanism and catalytic cycle, the catalytic nucleophile changes conformation dramatically during the reaction, Gln256 on the 250s loop is involved in orienting the substrate in the +1 site. The absence of a suitable base in the covalent intermediate structure explains the low hydrolysis activity, overview |

| 2.4.1.25 | maltononaose + maltotriose = maltoundecaose + D-glucose |
this entry covers the former separate entry for EC 2.4.1.3. (amylomaltase). The plant enzyme has been termed D-enzyme. An enzymic activity of this nature forms part of the mammalian and yeast glycogen debranching system (see EC 3.2.1.33 amylo-1,6-glucosidase) |
