DESCRIPTION

Also known as OL4AG_CELJU, agd31B. Alpha-transglucosylase that specifically transfers single glucosyl units from alpha(1->4)-glucans to the non-reducing terminal 4-OH of glucose and alpha(1->4)- and alpha(1->6)-linked glucosyl residues. Acts on amylose, amylopectin, glycogen and maltooligosaccharides, with the highest activity with maltotriose as a donor, and also accepts maltose. Does not act as a hydrolase: weak hydrolysis activity is only observed on the disaccharide maltose.
