The Article related to photoactive yellow protein photochem photophys chromophore model bridged compound, General Biochemistry: Proteins and Their Constituents and other aspects.HPLC of Formula: 53724-96-2

On October 6, 2005, El-Gezawy, Hani; Rettig, Wolfgang; Danel, Andrzej; Jonusauskas, Gediminas published an article.HPLC of Formula: 53724-96-2 The title of the article was Probing the Photochemical Mechanism in Photoactive Yellow Protein. And the article contained the following:

Selectively bridged model compounds related to the chromophore in photoactive yellow protein have been synthesized where the single bond adjacent to the benzene ring (bond 1) and where both bond 1 and the adjacent double bond (bond 2) are bridged. They were compared to the nonbridged reference compound regarding their photophys. properties using steady-state and time-resolved fluorescence at various temperatures Quantum chem. calculations were addnl. performed and showed that several conformers are populated in the ground state. The neutral model compounds show that the nonradiative deactivation channel is linked to both single- and double-bond twisting. The relative importance of single-bond twisting is increased for the corresponding deprotonated hydroxy compounds with an enhanced donor character. The simultaneous photochem. activity of both single and double bonds explains the ease of photochem. isomerization in the confined environment of the natural PYP protein and also of the primary step in the vision process in rhodopsin. The experimental process involved the reaction of Ethyl 6-methoxy-3-methylbenzofuran-2-carboxylate(cas: 53724-96-2).HPLC of Formula: 53724-96-2
