Crude Enzyme Solution

The ginsenoside-hydrolyzing β-glucosidase that can converse the major ginsenosides into the minor ginsenosides was isolated from wheat bran, and the enzyme was purified and characterized. The crude enzyme solution extracted from wheat bran could hydrolyse the protopanaxadiol-type ginsenosides such as Rb1, Rc, Rd and Rg3, but could not hydrolyse the protopanaxatriol-type ginsenosides such as Re and Rg2. The enzyme fractionated on the DEAE-Cellulose DE-52 column was purified to one spot in SDS polyacrylamide gel electrophoresis, and the molecular weight of enzyme in the fraction 34, 47, and 61 was approximately 62 kDa, 62 kDa, and 68 kDa, respectively.

Type Plasminogen Activator

SummaryTissue-type plasminogen activator (TPA) was purified from maxillary mucosa with chronic inflammation and compared with urokinase. Purification procedure consisted of the extraction from delipidated mucosa with 0.3M potassium acetate buffer (pH 4.2), 66% saturation of ammonium sulfate, zinc chelate-Sepharose, concanavalin A-Sepharose and Sephadex G-100 gel filtration chromatographies.The molecular weight of the TPA was approximately 58,000 ± 3,000. Its activity was enhanced in the presence of fibrin and was quenched by placental urokinase inhibitor, but not quenched by anti-urokinase antibody. The TPA made no precipitin line against anti-urokinase antibody, while urokinase did.All these findings indicate that the TPA in maxillary mucosa with chronic inflammation is immunologically dissimilar to urokinase and in its affinity for fibrin.
