Characteristics of two rice α-amylases Amy1A and Amy3D, and those of two chimeric enzymes Amy1A/3D and Amy3D/1A, engineered from the two isozymes, were compared in the light of the functional roles of protein domains in α-amylase. The enzymes that have an Amy1A-type N-terminal domain, Amy1A and Amy1A/3D, showed high activity against soluble starch, while the enzymes that have an Amy3D-type barrel structure, Amy3D and Amy1A/3D, showed high activity in oligosaccharide hydrolysis. Rigidity of… CONTINUE READING
