WebAug 6, 2008 · The vast majority of enzyme-coupled assays involve an oxido-reductase, usually an alcohol dehydrogease , using NAD or NADP as cofactors, as exemplified recently in the selection of enantioselective aldolase mutants. 91,92 Recent interesting examples include the determination of the enantioselectivity of lipases and esterases using acetate … WebThe Phosphofructokinase Colorimetric Assay kit provides a simple and direct procedure for measuring PFK activity in a variety of samples. PFK activity is determined by a coupled enzyme assay, in which fructose-6-phosphate and ATP is converted to fructose-1,6-diphosphate and ADP by PFK. The ADP is converted by the enzyme mix to AMP and …
