Proton-coupled electron transfers (PCETs) are unconventional redox processes in which
both protons and electrons are exchanged, often in a concerted elementary step. While …

Discussions of biochemical fluorescence frequently start with the subject of protein
fluorescence. This is because, among biopolymers, proteins are unique in displaying useful …

In this study, several proteins (albumin, lysozyme, insulin) and model compounds (Trp, Tyr,
homopolypeptides) were used to demonstrate the origin of the fluorescence observed upon …

Many proteins in living cells coordinate cofactors, such as metal ions, to attain their activity.
Since the cofactors in such cases often can interact with their corresponding unfolded …

In our previous paper (Reshetnyak, Ya. K., and EA Burstein. 2001. Biophys. J. 81: 1710–
1734) we confirmed the existence of five statistically discrete classes of emitting tryptophan …

Synchronous fluorescence spectra are performed by simultaneously scanning both the
excitation and emission wavelengths, and are widely used to analyze complex mixtures of …

Photonics of biopolymers discusses the processes of energy transformation in photoexcited
proteins, nucleic acids, membranes and model systems. The author addresses, among other …

The unfolding by guanidine hydrochloride (GuHCl) and the refolding on dilution of zinc and
apoazurin have been monitored by far-UV circular dichroism (CD). With the native protein …

We demonstrated that β-(1-azulenyl)-L-alanine, a fluorescent pseudoisosteric analog of
tryptophan, exhibits weak environmental dependence and thus allows for using weak …

The tumor-suppressor protein p53 is a major player in regulation of cell growth, genomic
stability, and cell death. Recent work suggests that Pseudomonas aeruginosa azurin, as the …
