Evaluation of camphor derivatives in terpenoid synthesis
New enantiospecific syntheses of 5,6-dehydrocamphor (36) and 5-methy1-5,6-dehydrocamphor (178) are reported, and these two compounds were evaluated as intermediates in terpenoid synthesis. Addition of an alkenyl unit to (+)-5,6-dehydro-camphor (36) and subsequent anionic oxy-Cope rearrangement of …

A kinetic and equilibrium description of camphor hydroxylation by the P450cam monoxygenase system
Camphor is hydroxylated in the soil bacterium Pseudomonas putida by a soluble three protein monoxygenase system consisting of (1) a NADH-specific FAD flavoprotein reductase, (2) a Fe2S*2 Cys4 iron-sulfur redoxin termed putidaredoxin (Pd) and (3) cytochrome P450cam, abbreviated cytochrome m for …

The treatment of the epileptic insane by the administration of borax, belladonna, bromide of camphor, and bromide of potassium
Almost as far back as we have records of events the story of the disease called Epilepsy reaches. Long before Medicine, as we know it at the present day, took the shape which separated it from Witchcraft and Sorcery, civil writings incidentally spoke of it, or gave it a name which in its meaning …

Genetic Variants in the Putidaredoxin-Cytochrome P-450(cam) Electron Transfer Complex: Identification of the Residue Responsible for Redox-State Dependent Complex Stabilization
Camphor is hydroxylated in Pseudomonas putida by a three component system comprised of an oxidase, cytochrome P-450$\sb{\rm cam},$ and a two-protein electron transfer chain, putidaredoxin and putidaredoxin reductase (Tyson et al., (1972) J Biol. Chem. 274, 5777-5784). The enzymatic removal of …

Proton relaxation studies of the interaction of small molecules with cytochrome P450
… following results are obtained: The substrate (camphor) complex of P450, which is in a mainly high-spin ferric state, has little effect on H20 relaxation times, suggesting that the heme iron may be five-coordinate. On the other hand, the native, predominantly low-spin P450 has a large effect on …
