Physical parameters and chemical composition of porcine pancreatic elastase II.

Some molecular properties of the elastase II preparation, homogenous in ultracentrifugation, have been determined. The molecular weight is 25 000, the sedimentation coefficient and the diffusion coefficient are 3.69-10(-13) s(-1) and 12.09-10(-7) cm2/s, respectively. The partial specific volume was 0.716 g/cm3, and the axial ratio is 1.95. Elastase II exhibited a considerably lower content of arginine, tyrosine, and valine, and a higher content of proline, serine and conjugated carbohydrates than elastase I. The N-terminal amino acid of the enzyme is leucine, and its isoelectric point was 10.7.
