| - | [[ | + | [[https://www.uniprot.org/uniprot/OL4AG_CELJU OL4AG_CELJU]] 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.<ref>PMID:23132856</ref> |
