gene Avin_08330 encodes the putative sucrose isomerase AZOG in the nitrogen-fixing bacterium Azotobacter vinelandii. The enzyme is a type of pseudo-sucrose isomerase harboring the RLDRD motif, a sucrose isomerase-specific region in 329-333. Neither sucrose isomerization nor hydrolysis activities are observed in recombinant AZOG (rAZOG). The rAZOG shows similar substrate specificity to the enzyme from Bacillus sp. O16G as it catalyzes the hydrolysis of isomaltulose and isomaltose, which contain alpha-1,6-glycosidic linkages. rAZOG generates isomaltose from the small substrate methyl-alpha-glucoside (MaG) via intermolecular transglycosylation. In addition, sucrose isomers isomaltulose and trehalulose are produced when 250 mM fructose is added to the MaG reaction mixture. Enzyme substrate specificity, overview. No activity with trehalose, maltose, nigerose, turanose, and panose. Comparison of substrate specificity with oligo-1,6-glucosidase, EC 3.2.1.10, from Bacillus halodurans strain O16G, UniProt ID BH2903, gene BH2903

Paraburkholderia acidicola
the isomaltulose-producing enzyme from Pseudomonas mesoacidophila MX-45 shows the main product trehalulose. It is also named alpha-glucosyltransferase and is renamed trehalulose synthase

-
Paraburkholderia acidicola
the enzyme catalyzes the enzymatic rearrangement of the alpha-1,2 linkage between glucose and fructose to an alpha-1,6 linkage (producing isomaltulose) or alpha-1,4 linkage (producing trehalulose). In addition, the enzyme hydrolyzes sucrose to produce small amounts of glucose and fructose monosaccharides
