  • Title: Glycosyltransferases as biocatalysts.
    Author: Palcic MM.
    Journal: Curr Opin Chem Biol; 2011 Apr; 15(2):226-33. PubMed ID: 21334964.
    Abstract:
    Glycosyltransferases are useful synthetic tools for the preparation of natural oligosaccharides, glycoconjugates and their analogues. High expression levels of recombinant enzymes have allowed their use in multi-step reactions, on mg to multi-gram scales. Since glycosyltransferases are tolerant with respect to utilizing modified donors and acceptor substrates they can be used to prepare oligosaccharide analogues and for diversification of natural products. New sources of enzymes are continually discovered as genomes are sequenced and they are annotated in the Carbohydrate Active Enzyme (CAZy) glycosyltransferase database. Glycosyltransferase mutagenesis, domain swapping and metabolic pathway engineering to change reaction specificity and product diversification are increasingly successful due to advances in structure-function studies and high throughput screening methods.
