Serial femtosecond X-ray structure of a fluorescence optimized bathy phytochrome PAiRFP2 derived from wild-type Agp2 in I6 intermediate state.

3-[(2Z)-2-({3-(2-carboxyethyl)-5-[(E)-(4-ethenyl-3-methyl-5-oxo-1,5-dihydro-2H-pyrrol-2-ylidene)methyl]-4-methyl-1H-pyrrol-2-yl}methylidene)-5-{(Z)-[(3E,4S)-3-ethylidene-4-methyl-5-oxopyrrolidin-2-ylidene]methyl}-4-methyl-2H-pyrrol-3-yl]propanoic acid

Serial-femtosecond crystallography reveals how a phytochrome variant couples chromophore and protein structural changes.
