THE primary photochemical event in visual pigments has become a matter of considerable controversy1–3. We recently reviewed the various models that have been proposed and argued that the accumulated evidence strongly favours the original suggestion of Kropf and Hubbard that the primary step involves a cis-trans isomerisation4. Evidence for isomerisation is based on the photoequilibrium that can be established, both at 77 K (ref. 5) and at room temperature6, between rhodopsin, bathorhodopsin… CONTINUE READING
