DE   beta-1,2-glucosyltransferase.
CA   [(1->2)-beta-D-glucosyl]n + a D-glucoside = [(1->2)-beta-D-glucosyl]n-1 +
CA   a beta-D-glucosyl-(1->2)-D-glucoside.
CC   -!- The enzyme, characterized from the bacterium Ignavibacterium album,
CC       transfers a glucosyl residue from the non-reducing end of a 1,2-beta-
CC       D-glucan to a glucose residue of an acceptor molecule, forming a
CC       beta(1,2) linkage.
CC   -!- The donor molecule can be as small as sophorose (which contains two
CC       glucosyl residues).
CC   -!- The enzyme has a very broad specificity for the acceptor, and can act
CC       on various aryl- and alkyl-glucosides.
CC   -!- In addition, the accepting glucose unit can be in either alpha or
CC       beta configuration.
