Substrate specificities
Glycoside hydrolase family 77 is the member of the α-amylase clan GH-H [1], together with GH13 and GH70 [2]. The family contains only one enzyme specificity - the amylomaltase (EC 2.4.1.25), that is known as disproportionating enzyme (D-enzyme) in plants [3] or 4-α-glucanotransferase in bacteria [4] and archaeons [5]. As of April 2010, it has more than 700 members [1] with more than 650 from Bacteria, ~10 from Archaea and a few tens from Eukarya (plants and green algae).
