Purification and characterization of histidine decarboxylase from mouse kidney.
Histidine decarboxylase was purified 800-fold from the kidneys of thyroxine-treated mice. The purification procedure included precipitation of protein from a crude supernatant after heating it to 55 degrees C at pH 5.5, fractionation with (NH4)2SO4, phosphocellulose column chromatography, chromatofocusing, DEAE-Sepharose column chromatography, gel filtration on Sephacryl S-300 and preparative p...
متن کاملPurification and Characterization of Mouse Kidney ,&Glucuronidase
P-Glucuronidase has been purified from mouse kidneys previously induced by gonadotrophin to a specific enzyme activity 15 times higher than the non-induced kidney. The purification procedure includes ultrasonication to solubilize the enzyme, acid and ammonium sulfate precipitations, gel filtration in Sephadex G-200, DEAE-ion exchange chromatography, and isoelectric focusing. The resulting produ...

متن کاملPurification and characterization of a metallo-endoproteinase from mouse kidney.
A metallo-endoproteinase was purified from mouse kidney. The enzyme was solubilized from the 100 000 g sediment of kidney homogenates with toluene and trypsin, and further purified by fractionation with (NH4)2SO4. DEAE-cellulose chromatography and gel filtration. The molecular weight of the metalloproteinase was estimated by gel filtration on Sepharose 6B to be 270 000--320 000. On sodium dodec...
متن کاملPurification and characterization of mouse mevalonate pyrophosphate decarboxylase.
Mevalonate pyrophosphate decarboxylase (MPD) in mouse liver was purified by affinity chromatography. The purified enzyme was a homodimer of 46-kDa subunits and had an isoelectric point of 5.0. Kinetic analysis revealed an apparent Km value of 10 microm for mevalonate pyrophosphate. The enzyme required ATP as a phosphate acceptor and Mg as a divalent cation, which could be substituted with Mn or...
