Microsomal heme oxygenase. Characterization of the enzyme.
Abstract This study characterizes microsomal heme oxygenase, a previously undescribed enzyme which catalyzes the oxidation of heme at the α-methene bridge to form biliverdin. This step is thenExpand

Acute porphyria: treatment with heme.
The characterization of porphyrias as disorders of heme biosynthesis leading to hepatic heme deficiency and raised formation and secretion of heme precursors laid the basis for heme treatment.Expand

Haem arginate: a new stable haem compound
Intravenous administration of haem in acute hepatic porphyrias inhibits the induction of β‐aminolaevulinic acid synthase, reduces the formation of potentially harmful metabolites of porphyrinExpand

Spectral and other studies on the intestinal haem receptor of the pig.
We recently demonstrated the presence of a Triton-solubilized high-affinity haem binder on the pig duodenal brush border membrane. The association of haem to the binding factor was determined usingExpand
