DOI: 10.1128/jb.00300-22
Abstract: Photoactive yellow protein is a model bacterial photoreceptor. For many years, it was considered a prototypical model of the ubiquitous PAS domain superfamily. Here, we show that, in fact, the PYP family is evolutionarily novel,… read more here.

DOI: 10.3390/molecules26154554
Abstract: The mechanism by which proteins are solvated in hydrated ionic liquids remains an open question. Herein, the photoexcitation dynamics of photoactive yellow protein dissolved in hydrated choline dihydrogen phosphate (Hy[ch][dhp]) were studied by transient absorption… read more here.
