Abstract
In the absence of the natural acceptor inorganic phosphate wild-type sucrose phosphorylase from Bifidobacterium adolescentis (BaSP) produces maltose (4-O-α-d-glucopyranosyl-d-glucose) and kojibiose (2-O-α-d-glucopyranosyl-d-glucose) as sole transfer products. A Q345F exchange switches the enzyme's regioselectivity from 2 to 3 exclusively, yielding the rare sugar nigerose (3-O-α-d-glucopyranosyl-d-glucose, sakebiose).
