Figure 1
Structure of Chlamydomonas LOV1 2.5 ms after light activation. The FMN-Cys57 thioether covalent adduct is clearly visible in the electron density (transparent blue). The FMN and Cys57 are marked. Residue numbers are marked (from 21 to 122) to help tracing the amino acid backbone from the N- to the C-terminus. Dotted blue line: the loop is removed to allow for an unperturbed view on the FMN binding pocket. Structure and structure factors obtained from PDB entry 8qia. |
