Abstract:
Bovine liver alkaline phosphatase has been purified to homogeneity by procedures that include reverse-phase HPLC. The pure enzyme has an apparent Mr of 160,000 and is composed of what appears to be two identical monomers of Mr 82,000. About 80% of the material yielded the amino-terminal sequence Leu-Val-Pro-Glu-Lys-Glu-Lys-Asp-Pro-?-Tyr-?-Arg-Asp-Gln-Ala-Gln. The minor component was extended at the amino terminus by two residues that have not yet been identified, i.e., ?-?-Leu-Val-Pro-Glu-Lys-Glu-Lys-Asp-Pro-?-Tyr-?-Arg-Asp-Gln-Ala-Gln.
