WebSep 5, 2024 · The cyto-phosphatase PHOSPHO1 generates phosphate from membrane phospholipid C through hydrolyzed phosphocholine and phosphoethanolamine. Type III Na/Pi cotransporter is also given for phosphates both on the cell membrane and on the vesicle matrix membrane. 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. WebEukaryotic protein phosphatases are structurally and functionally diverse enzymes that are represented by three distinct gene families. Two of these, the PPP and PPM families, … green man gaming minecraft
