Prostatic acid phosphatase (EC 3.1.3.2) purified from benign hypertrophic prostate tissue was fractionated by preparative slab isoelectric focusing over a pH gradient of 3.16 to 7.16. Twenty-two of 29 fractions contained enzyme activity. We further examined each active fraction by determining the Michaelis-Menten constant and specific activity. The protein concentration used in the latter deter...

The snake venom´s thrombin-like enzymes comprise a number of serine proteases, which are functionally and structurally related to thrombin. Purification and partial characterization of a thrombin-like enzyme from the venom of the Iranian snake, Agkistrodon halys, was the aim of this study. Purification was carried out by a combination of variety of chromatographic methods that included: gel...
