Characterization of an alkaline subtilopeptidase type Pfizer
The physiochemical properties, amino acid composition and profile of the the tryptic peptides for an alkaline subtilopeptidase type Pfizer have been determined. The enzyme is stable in the pH range from 5 to 10, has a pH optimum of 9.5 to 10, and is relatively stable for a period of 2 h up to a temperature of 50C. Homogeneity was demonstrated by electrophoretic techniques and the mobilities indicated on isoelectric point of 8.7. The molecular weight was found to be 25,000 by gel filtration. The amino acid composition was found to be Ala32, Arg4, Aspgamma8, Glu15, Gly29, His4, Ile9, Leu13, Lys11, Met5, Phe4, Pro14, Ser31, Thr17, Tyr9, Val22, a total of 247 amino acid residues. The enzyme does not contain either disulfide bonds or cysteine, and lacks tryptophan as well. The N-terminal end-group residue is alanine: the C-terminal amino acid is arginine. Tryptic hydrolysis of the enzyme produced 15 peptides which were separated by gradient elution on Dowex 50-X2. The amino acid composition of each appropriately purified tryptic peptide was established.
