Chemical dynamics in proteins are discussed, with bacteriorhodopsin serving as a model system. Ultrafast time-resolved methods used to probe the chemical dynamics of retinal photoisomerization in bacteriorhodopsin are discussed, along with future prospects for ultrafast time-resolved crystallography. The photoisomerization of

Bacteriorhodopsin (bR) is characterized by a retinal-protein protonated Schiff base covalent bond, which is stable for light absorption. We have revealed a light-induced protonated Schiff base hydrolysis reaction in a 13-cis locked bR pigment (bR5.13; lambda(max) = 550 nm) in

Bioconjugates of a polyamidoamine (PAMAM) G3 dendrimer and an aldehyde were synthesized as carriers for vitamins A and B₆, and the bioavailability of these vitamins for skin nutrition was investigated. Nuclear magnetic resonance (NMR) and ultraviolet-visible methods were used to

Optical control of the primary step of photoisomerization of the retinal molecule in bacteriorhodopsin from the all-trans to the 13-cis state was demonstrated under weak field conditions (where only 1 of 300 retinal molecules absorbs a photon during the excitation
J K McBee et al.
Biochemistry, 39(37), 11370-11380 (2000-09-14)
In the retinal rod and cone photoreceptors, light photoactivates rhodopsin or cone visual pigments by converting 11-cis-retinal to all-trans-retinal, the process that ultimately results in phototransduction and visual sensation. The production of 11-cis-retinal in adjacent retinal pigment epithelial (RPE) cells

Retinoic Acid and Gene Expression

All-trans retinoic acid (RA, ATRA) is a pleiotropic activation factor that regulates genes associated with normal vertebrate cellular processes such as cell differentiation, cell proliferation, apoptosis, and embryonic development.
