Specific activity formula enzyme
WebMay 15, 2015 · The enzyme catalysis reaction following MM kinetics can be depicted as: $$\Large\ce{E + S<=>[k_f][k_r]ES->[k_{cat}]E + P }$$ Note that $V_{max} = k_{cat}.[E_0]$ i.e. conversion rate constant (turnover number) times the total amount of enzyme. You … WebA measurement of specific activity is used to describe the purity of an enzymatic mixture. The specific activity is equal to the activity of an enzyme per milligram of total protein in the mixture. Cooperativity is a unique type of allosteric regulation observed in proteins composed of multiple identical subunits.
