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. Typical uses in the lab for alkaline phosphatases include removing phosphate monoesters to prevent self-ligation, which is undesirable during plasmid DNA cloning.
Web8 ian. 2024 · Therefore, most of the tests for phosphatase in milk are based on the principle that ALP will hydrolyze monophosphate esters at an appropriate temperature and pH, thereby liberating compounds that can be detected by color development. The intensity of color developed is proportional to the activity of the enzyme.
