The N-terminally truncated enzyme GtfB of Lactobacillus reuteri strain 121 is member of the GH70 family. This 4,6-glucanotransferase is active on malto-oligosaccharides and starch, thereby yielding elongated isomalto/malto-oligomers (IMMOs)/polymers (IMMPs) containing α(1→4) and α(1→6) glycosidic linkages. The conversion of maltoheptaose (DP 7) using the GtfB of L. reuteri 121 ends up in products with a DP > 35.

The GtfD enzyme of Azotobacter chroococcum is member of the glycoside hydrolase family GH70. The enzyme displays 4,6-α-glucanotransferase activity using malto-oligosaccharides (> DP 4), and starch. However, the enzyme is unable to synthesize consecutive α(1→6) glucosidic bonds. Instead it forms a high molecular mass, α(1→4,6) branched reuteran like polymer.
