General description
Alkaline phosphatase from calf intestine is a glycoprotein with a molecular weight of 140,000.
Application
Alkaline phosphatase from calf intestine, CIP, removes phosphate groups from the 5′ ends of DNA which aids in cloning techniques to keep DNA from self-ligation. It can be inhibited by homoarginine.
Calf intestinal alkaline phosphatase (CIAP) has been used in a study with the spectrophotometric method to assess the inhibition effect of dansyl-L-phenylalanine. It has also been shown that (CIAP) is able to detoxify the lipopolysaccharide (LPS)-mediated inflammatory response, which could be important in the treatment of LPS-mediated diseases.
Biochem/physiol Actions
Sigma insoluble enzymes are produced by reacting the conventional "soluble" enzyme with an inert base that results in an insoluble compound retaining the activity of the original enzyme. Applications are almost unlimited. By selecting the "inert" base carefully, a highly active "resin" or "gel" can be produced with which the enzyme reaction can be quickly catalyzed by momentary contact with the substrate in a suitable medium. This can be carried out either in a batch slurry or even through a small column. In either case, the insoluble enzyme does not remain as a contaminant of the reaction mix. It can be readily filtered or centrifuged out of the batch slurry, or remain behind in the column. Many unstable enzymes seem to be much more stable in the insoluble form.

To evaluate the inhibition effect of dansyl-L-phenylalanine on calf intestinal alkaline phosphatase (CIAP), UV-Vis spectrophotometric method was employed. It was found that dansyl-L-phenylalanine can selectively inhibit CIAP. The kinetic inhibition processes of dansyl-L-phenylalanine and L-phenylalanine were comparatively studied. The authors'
