GtfB-ΔN of Lactobacillus reuteri strain NCC 2613

175.00525.00

The N-terminally truncated GtfB enzyme of Lactobacillus reuteri NCC 2613 is a member of the GH70 family. The 4,6-α-glucanotransferase converts amylose, amylopectine, potato starch, and malto-oligosaccharides with a degree of polymerization (DP) of 5 to 7 in a low molecular mass reuteran-like polymer containing 75 % α(1→4) and 25 % α(1→6) glucosidic linkages, and α(1→4,6) branching points. The Lactobacillus reuteri NCC 2613 enzyme possesses the Generally Recognized As Safe (GRAS) status, making it an interesting product for the food industry. There are a lot of differences between the products formed by the 4,6 glucanotransferase GtfB subfamily. GtfB strain 121 formes a long linear consecutive polymer with α(1→6) linkages (IMMP), whether the glucan of strain NCC 2613 is branched and has a low molecular weight.

*Activity was measured by following the release of glucose from amylose. One unit of enzyme activity is defined as the release of 1 μmol of substrate per minute.
