WebYour formula for getting k cat from V max depends on the enzyme being 100% pure and 100% active, as discussed before. Prima facie evidence for this would be one band only in SDS-PAGE ... WebPurity of the enzyme preparations The enzyme preparations need not be of the highest purity, since neither sedoheptulose diphosphate nor other phosphate esters form glucose-6-phosphate. However, the preparations must be free from non-specific phosphatases, because hydrolysis of fructose-1,6-diphosphate at the C-6-phosphate group would result …
