We have cloned, overexpressed, purified, and characterized a 2-ketogluconate kinase (2-dehydrogluconokinase, EC 2.7.1.13) from Cupriavidus necator (Ralstonia eutropha) H16. Exploration of its substrate specificity revealed that three ketoacids (2-ket

Limitations to concurrent reactions involving hybrid catalysis, such as acidic pH, elevated temperature and catalyst incompatibilities, were overcome by immobilizing cells harbouring the enzyme, and compartmentalizing catalysts.

Aldolases are powerful C-C bond-forming enzymes in biocatalysis because of their unparalleled stereoselectivity, the ease with which reactions that do not require cofactor recycling can be set up, the large number of different types and families avai

Asymmetric aldol addition of simple aldehydes and ketones to electrophiles is a cornerstone reaction for the synthesis of unusual sugars and chiral building blocks. We investigated D-fructose-6-phosphate aldolase from E. coli (FSA) D6X variants as ca
