Partial purification and characterization of cresolase and catecholase activity of black mulberrys (Morus nigra)
Polyphenol oxidase from Black mulberrys was extracted and partially purified through (NH4)2SO4 precipitation, dialysis and ion exchange chromatography. P-cresol was the better substrate for cresolase activity with a Km (11.5 mM) and catechol for catecholase activity with Km (6.4 mM) at pH 5. Km for cresolase and catecholase activity of IsoPPOII at pH 6.5 were 12 and 8.5 and for IsoPPOIII at pH ...
متن کاملPartial purification and characterization of bovine liver aspartyl beta-hydroxylase.
In vitro hydroxylation of aspartic acid has recently been demonstrated in a synthetic peptide based on the structure of the first epidermal growth factor domain in human factor IX (Gronke, R. S., VanDusen, W. J., Garsky, V. M., Jacobs, J. W., Sardana, M. K., Stern, A. M., and Friedman, P. A. (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 3609-3613). The putative enzyme responsible for the posttransla...
متن کاملPARTIAL PURIFICATION AND CHARACTERIZATION OF B-GALACTOSIDASE FROM ASPERGILLUS NIGER UV-5
The enzyme pgalactosidase from a mutant strain of A. niger UV-5 was partially purified using ammonium sulfate and acetone. The saturation range of 60-80% ammonium sulfate was found to yield 60.5% enzyme recovery with 2.4 fold purification. Acetone precipitation at enzyme: acetone ratio of 1 : 1.5 brought about a higher yield i.e. 68% and three-fold purification. The combined procedures of ...
متن کاملPURIFICATION AND PARTIAL CHARACTERIZATION O F PEROXIDASES FROM CULTIVATED RAPHANUS SATIVUS L. VAR. CICIL
Two peroxidases (EC. 1.11.1.7), POD I and POD II were purified from the roots of cultivatedRaphanus sativus L. Var. Cicil by one step ion-exchange chromatography after fractionation by acetone. The molecular weight of these enzymes were 43000 and 41000 Daltons and RZ 1.2 and 2.0 for POD I and POD II, respectively. Both enzymes consisted of a single polypeptide chain on SDS-PAGE. The maximum...
متن کاملPartial Purification and Characterization of Anticoagulant Factor from the Snake (Echis carinatus) Venom
Objective(s): Snake venoms contain complex mixture of proteins with biological activities. Some of these proteins affect blood coagulation and platelet function in different ways. Snake venom toxin may serve as a starting material for drug design to combat several pathophysiological problems such as cardiovascular disorders. In the present study, purification of anticoagulation facto...
