Artificial Fusion of mCherry Enhances Trehalose Transferase Solubility and Stability.

ABSTRACT: LeLoir glycosyltransferases are important biocatalysts for the production of glycosidic bonds in natural products, chiral building blocks, and pharmaceuticals. Trehalose transferase (TreT) is of particular interest since it catalyzes the stereo- and enantioselective α,α-(1→1) coupling of a nucleotide sugar donor and monosaccharide acceptor for the synthesis of disaccharide derivatives. Heterologously expressed thermophilic trehalose transferases were found to be intrinsically aggregation prone and are mainly expressed as catalytically active inclusion bodies in Escherichia coli To disfavor protein aggregation, the thermostable protein mCherry was explored as a fluorescent protein tag. The fusion of mCherry to trehalose transferase from Pyrobaculum yellowstonensis (PyTr
