    Research output: Contribution to journalArticlepeer-review


    Squid retinal will yield energy during the conformational change from the 11-cis-retinal to alltrans-retinal. The retinal that we investigate here, 4WW3, accepts light near 500 nm. Using the Planck-Einstein relationship E=hv, the absorption energy is about 4×10^-19 J. The identification in the Protein Data Bank (PDB) of 4WW3 is appeared in the last year. The analyses of 4WW3 here are the same as our previous analysis for 2Z73, 2ZIY, 3AYM, and 3AYN.
