Directed Mutation of Two Key Amino Acid Residues Alters the Product Structure of the New 4,6-α-Glucanotransferase from Bacillus sporothermodurans.

Abstract excerpt

4,6-α-Glucanotransferases (4,6-α-GTs) convert amylose V into two types of differently structured products: a linear product connected by continuous α,1 → 6 bonds, such as isomalto/malto-polysaccharide (IMMP), and a highly branched product connected by alternating α,1 → 4 and α,1 → 6 bonds, such as reuteran-like polysaccharide (RLP). The synthesis process of 4,6-α-GT products is unclear, and exploring this process...
