WebMar 17, 2024 · This is a good interpretation. kcat/Km is a useful measure of the efficiency of the enzyme because it considers both the maximal rate of the enzyme kcat, as well as the affinity of the enzyme for its substrate (Km). More efficient enzymes will have high kcat values (the enzyme can react with its substrates quickly) and low Km values (the enzyme ...
