Investigation of the Effect of the NH center dot center dot center dot OC Hydrogen Bond from Cys69 to PYP Chromophore Using Novel Active-center Model Compound

Okamoto K, Hamada N, Sumi T, Okamura T, Ueyama N, Yamamoto H

A PYP active-center model compound containing a hydrogen bond to the conjugated carbonyl oxygen was synthesized and its effect on the electronic properties of the chromophore were investigated. The intramolecular hydrogen bond induces significant change in the absorption maximum of the pi-pi* transition in the chromophore.
