(3-Hydroxy-2-naphthalenyl)methyl (NQMP) group represents an efficient photo-cage for fluorescein - based dyes. Thus, irradiation of 6-NQMP ether of 2'-hydroxymethyl fluorescein with low-intensity UVA light results in 4 fold increase in emission intensity. Photoactivation of non-fluorescent NQMP-caged 3-allyloxyfluorescein produces highly emissive fluorescein mono ether. To facilitate conjugation of the caged dye ...

Cyanobacteriochromes (CBCRs) form a large, spectrally diverse family of photoreceptors (linear tetrapyrrole-covalently bound via a conserved cysteine) that perceive UV to far-red light. The underlying mechanisms are reasonably well understood with, in certain cases, reversible formation of an adduct between a second cysteine and the chromophore accounting, in part, for ...
