General description
Alkaline phosphatase from bovine intestinal mucosa is both a phosphomonoesterase and a pyrophosphatase.
Application
Alkaline phosphatase can be used to dephosphorylate casein and other proteins. Alkaline phosphatase may be also be used to dephosphorylate the 5′-termini of DNA or RNA to prevent self-ligation. DNA or RNA can also be tagged with radiolabeled phosphate (via T4 polynucleotide kinase) after dephosphorylation with alkaline phosphatase..
High specific activity grade recommended for antibody and protein conjugation.
Phosphatase alkaline from bovine intestinal mucosa has been used in a study to measure the hydrolysis kinetics of three polyfluorinated alkyl phosphate monoesters, differing in fluorinated chain length. It has also been used in a study to show that the developmentally controlled expression of the isosomes C-1 and C-2 indicate functional changes in intestinal alkaline phosphatase with tissue maturation.
Biochem/physiol Actions
Alkaline phosphatase was shown to have anti-inflammatory effects and can reduce the severity of septic shock by detoxifying lipid A.
The enzyme has a broad specificity for phosphate esters of alcohols, amines, pyrophosphate, and phenols. It is routinely used to dephosphorylate proteins and nucleic acids.
Physical properties
Bovine intestinal alkaline phosphatase is a dimeric, membrane-derived glycoprotein. At least three isoforms exist, which typically possess two N-linked and one or more O-linked glycans per monomer.

Unit Definition
One DEA unit will hydrolyze 1 μmole of 4-nitrophenyl phosphate per minute at pH 9.8 at 37 °C. (One glycine unit is equivalent to ~3 DEA units)
Physical form
