Partial purification and properties of rat liver mitochondrial polynucleotide phosphorylase.
1. Polynucleotide phosphorylase was partially purified from the inner membrane of rat liver mitochondria. 2. The partially purified particulate enzyme catalyses phosphorolysis of poly(A), poly(C), poly(U) and RNA to nucleoside diphosphates. 3. It is devoid of nucleoside diphosphate-polymerization activity. 4. Variable amounts of ADP/P(i)-exchange activity are associated with the polynucleotide ...
متن کاملPartial purification of mitochondrial RNA polymerase from rat liver.
Mitochondrial RNA polymerase activity from rat liver has previously been demonstrated in intact organelles. This activity has now been solubilized, partially purified, and shown to be a true polymerase, free of nuclease. The enzyme is derived from mitochondria and is not from contaminating bacteria or nuclear components. The enzyme is distinguished from its nuclear counterparts by its behavior ...
متن کاملPartial purification and properties of acid sphingomyelinase from rat liver.
Acid sphingomyelinase was purified approximately 5,200-fold from the mitochondria-lysosome-enriched particles of rat liver by sequential chromatography on DEAE-cellulose, octyl-Sepharose, Sephacryl S-300, Concanavalin A-Sepharose, and CM-cellulose. The specific activity of this highly purified enzyme was 3.2 mmol per hr per mg protein. The enzyme was active against 2-hexadecanoylamino-4-nitroph...
متن کاملPurification and general properties of the DNA-binding protein (P16) from rat liver mitochondria
The mitochondrial DNA-binding protein P16 was isolated from rat liver mitochondrial lysates by affinity chromatography on single strand DNA agarose and separated from DNA in the preparation by alkaline CsCl isopycnic gradients. The top fraction of the gradients contained a single polypeptide species (Mr approximately equal to 15,200) based upon SDS PAGE. Digestion of single strand DNA-bound P16...
متن کاملSolubilization and partial purification of heme oxygenase from rat liver.
Hepatic microsomal heme oxygenase was solubilized, partially purified, and characterized from Co2+-treated rats. The enzyme on sodium dodecyl sulfate-polyacrylamide gel electrophoresis exhibited a minimum molecular weight of greater than or equal to 68,000. The solubilized enzyme was totally devoid of contamination with cytochrome P-450 or b5. The requirement for reduced pyridine nucleotides wa...
