In this laboratory, we discovered, cloned, and expressed, an exceptionally robust Glucosidase enzyme (β-glucosidase from Streptomyces griseus (SgBgl)). Preliminary experiments showed that this enzyme could synthesise certain alkyl glucosides (biodegradable detergent made from glucose and alcohols) with unusually high yield, under mild conditions, in the presence of Deep Eutectic Solvents (DES).
However, this reaction was not optimized or extended to long chain derivatives. Reactions with alternative glycosyl donors or acceptors were not explored. This exciting finding opens a host of possibilities for Green Chemistry applications. Our preliminary studies show that this enzyme can be developed into a broadly useful biocatalyst by appropriate modification. Such a catalyst will have important applications in research and industry. We plan to optimize this enzyme and use it to synthesize biodegradable glycosides of various kinds. We will extend this to synthesis of industrially important bioactive glycoside derivatives.
By varying the glycosyl donor or acceptor a range of glycosylated products can, in principle, be synthesised. We are particularly interested in glycosylation of drugs, peptides and bioactives such as Quercetin, hydroxytyrosol, Daidzin
