Measurements of Photoreaction and Kinase Activity of Phototropin, a Photoreceptor Protein for Tropic Response in Plants: Involvement of Kinase Activity in the Photosensitivity of Tropic Responses, spectrophotometric and kinase activity analyses of phototropin are important to understand the light signaling processes related to the photosensitivity. The preparation of polypeptide samples of . phototropin and the methods of spectroscopic measurements and kinase assay of these samples are shown in this chapter. |
