Abstract

In the last few years sequencing projects have uncovered numerous prokary- otic genes which encode domains resembling the chromophore-bearing sensory module of plant phytochromes. The majority are from cyanobacteria, where up to 13 different proteins with such a domain have been found within a single species. Besides the chromophore region, many of these proteins contain PAS- and histidine kinase-like domains, both of which are also present in plant phytochromes. However, the diversity of this phytochrome-superfamily with respect to overall domain organisation and primary structure is much greater than that seen in plant phytochromes, thus offering a rich variety of strategies for research into the evolution, structure and function of the group as a whole. Based on sequence similarities and functional studies, two subgroups can be distinguished, the phytochrome-like proteins and the true phytochromes, the latter being defined by red/far-red photochromicity. To date the best analysed amongst the prokaryotic true phytochromes is Cphl from Synechocystis PCC 6803. Not only the primary structure but also many spectral and biochemical properties of Cphl are strikingly similar to those of plant phytochromes. Yet equally clear and perhaps even more interesting are the differences. Studies of more distantly-related phytochromes are also progressing rapidly, providing new vantage points for viewing structure-function relationships in the phytochrome superfamily as a whole.
