Chicken Intestinal Alkaline Phosphatase
Purified chicken intestinal alkaline phosphatase is active at pH 8 to 9, but becomes rapidly inactivated with change of pH to 6 or less. Also, a solution of the inactivated enzyme at pH 4.5 rapidly regains its activity at pH 8. In the range of pH 6 to 8 a solution of purified alkaline phosphatase consists of a mixture of active and inactive enzyme in equilibrium with each other. The rate of ina...

متن کاملIsozymes of bovine intestinal alkaline phosphatase.
Alkaline phosphatases from calf and bovine small intestines have been isolated in homogeneous form from both mucosa and luminal contents. The detergent-solubilized calf enzyme resolves into two peaks of activity, C-1 and C-2, on chromatofocusing. Only one of these activity peaks is present in the enzyme from the adult animal. Amino acid compositions, N-terminal sequences, and tryptic peptide ma...
متن کاملCharacterization of human foetal intestinal alkaline phosphatase
The molecular structure of human foetal intestinal alkaline phosphatase was defined by high-resolution two-dimensional polyacrylamide-gel electrophoresis and amino acid inhibition studies. Comparison was made with the adult form of intestinal alkaline phosphatase, as well as with alkaline phosphatases isolated from cultured foetal amnion cells (FL) and a human tumour cell line (KB). Two non-ide...
متن کاملNucleotide and amino acid sequences of human intestinal alkaline phosphatase: close homology to placental alkaline phosphatase.
A cDNA clone for human adult intestinal alkaline phosphatase (ALP) [orthophosphoric-monoester phosphohydrolase (alkaline optimum); EC 3.1.3.1] was isolated from a lambda gt11 expression library. The cDNA insert of this clone is 2513 base pairs in length and contains an open reading frame that encodes a 528-amino acid polypeptide. This deduced polypeptide contains the first 40 amino acids of hum...
