The Enzymic Conversion of Protoporphyrinogen IX to Protoporphyrin IX
The oxidation of protoporphyrinogen IX to protoporphyrin TX in yeast cells is enzyme-dependent. The enzyme, protoporphyrinogen oxidase, associated with purified mitochondria isolated from Saccharomyces cereuisiae was solubilized by sonic treatment in the presence of detergent and partially purified. The molecular weight of the enzyme was 180,000 f 18,000. The purified preparation could be store...
متن کاملEnzymic degradation of heparin.
A sulphamidase and a sulphoesterase were isolated from adapted cells of Flavobacterium heparinum. These enzymes were partially purified from the 'heparinases' present in the bacterial extracts and characterized. The sulphamidase has a high specificity for glucosamine N-sulphate and glucosamine 2,6-disulphate. The activity decreases sharply with increasing molecular weight ofthe substrates teste...

متن کاملThe enzymic conversion of protoporphyrinogen IX to protoporphyrin IX in mammalian mitochondria.
Protoporphyrinogen oxidase, an enzyme which catalyzes the oxidation of protoporphyrinogen IX to protoporphyrin IX in yeast cells, has been found in several mammalian tissues. It has been extracted from rat liver mitochondria by sonication in the presence of salt and detergent and partially purified. The enzyme is similar in many respects to yeast protoporphyrinogen oxidase. Based on its behavio...
متن کاملPart Ix Afterword
Someone has to go last and in this case the honor falls to Mike Byrne. I did not commission Mike to write “a last chapter” but that is what he did. In a way his chapter 30 and my chapter 1 can be viewed as bookends for the 28 chapters that lie between. I began the book with a short essay on three types of control of cognition that need to be considered when building integrated models of cogniti...
