Enzyme kinetics is an essential topic in undergraduate Biochemistry courses. pH conditions must be kept constant throughout using only pH of 11 for all temperature experiments. The reaction kinetics of alkaline phosphatase (ALP) adsorbed on paper was quantified by image analysis using a colorimetric technique. Alkaline phosphatase accounts for 6% of all proteins in derepressed cells. By changing the amino acids of the wild-type alkaline phosphatase enzyme produced by Escherichia coli, a mutant alkaline phosphatase is created which not only has a 36-fold increase in enzyme activity, but also retains thermal stability.
