Acceptor Subsite Mutants of Limosilactobacillus fermentum NCC 2970 GtfB 4,3-α-Glucanotransferase Regulate the Ratio of (α1 → 3)/(α1 → 6) Linkages in Biosynthesized α-Glucans.

Abstract excerpt

Limosilactobacillus fermentum NCC 2970 GtfB (Lf2970 GtfB) is the only characterized 4,3-α-glucanotransferase (4,3-α-GTase) in the glycoside hydrolase (GH) 70 family belonging to the GtfB subfamily. However, the mechanism for its (α1 → 3) linkage formation remains unclear, and the structural determinants of its linkage specificity remain to be explored. Here, sequence alignment and structural comparison were...
