Chemsitry and Biology of Synthetic Retinoids
reduction of the pKa of the protonated Schiff base as a consequence of light
absorption. Thus, understanding the factors influencing the pKa of model RSBH+
is a prerequisite for clarifying the retinal-opsin interactions that affect the pKa of

Light Sensing in Plants
The rhodopsin structure controls retinal Schiff-base hydrolysis, retinal release
and MII decay. The retinal Schiff-base linkage is dramatically stabilized in the
dark-state rhodopsin (the t1/2 for hydrolysis is days). In contrast, in MII rhodopsin,
the ...

Hydrogen Bonding and Transfer in the Excited State
It is believed that the interaction between the protonated Schiff base and Cl −
plays a crucial role in the vectorial transport of the chloride ion. Therefore, it is
essential experimentally to monitor the hydrogen-bonding strength of the Schiff
base ...

Bioconjugate Techniques
Carbonyl groups such as aldehydes, ketones, and glyoxals can react with
amines to form Schiff base intermediates which are in equilibrium with their free
forms. The interaction is pH dependent, being more efficient at low pH and
especially ...

Molecular Mechanisms in Bioenergetics
Small motions, involving a few amino acids or a slight helix tilt, were observed
near the Schiff base and the /3-ionone ring of retinal. Small differences between
bR and M were also observed by electron cryomicroscopy at 3.3 A resolution [
