Abstract excerpt
Four xylanases belonging to glycoside hydrolase family 10-Thermotoga maritima XylB (TM), Clostridium stercorarium XynB (CS), Bacillus halodurans XynA (BH), and Cellulomonas fimi Cex (CF)-were converted to glycosynthases by substituting the nucleophilic glutamic acid residues with glycine, alanine, and serine. The glycine mutants exhibited the highest levels of glycosynthase activity with all four enzymes. All the...
