Substrate interactions in cytochrome P-450: correlation between carbon-13 nuclear magnetic resonance chemical shifts and C-O vibrational frequencies.
13CO NMR chemical shifts and 12CO infrared stretching frequencies have been measured for cytochrome P-450cam-CO in the presence of D-camphor and of various camphor analogues. A linear correlation between both parameters delta (13C) and v(CO) was found indicating that the steric and electrostatic interactions acting on the CO ligand are influenced by the substrate. It has been proved that P-450 ...
متن کاملNuclear magnetic resonance spectroscopy. Ring-current effects on carbon-13 chemical shifts.
A comparison of the (13)C nuclear magnetic resonance chemical shifts of some 15,16-dialkyl-15,16-dihydropyrenes with the corresponding 15,16-dialkyl-2,7,15,16-tetrahydropyrenes provides a measure of the effect of ring current on carbon-13 chemical shifts in which other effects may be expected to be negligibly small. The general conclusion is that the absolute magnitude of the ring-current effec...
