The photodynamic action of several dyes on cells of a bacterium, tentatively identified as a species of Arthrobacter, resulted in remarkable stimulation of synthesis of a polypeptide 21,000 daltons in mass. This polypeptide resides on the cell surface and can be solubilized by sodium dodecyl sulfate without lysis of the cells. Chlorophyllin and rose bengal are effective in inducing synthesis of the polypeptide in proportion to their ability to sensitize the photooxidation of histidine. Etiolated cells of the alga Chlamydomonas reinhardtii y-1 excrete a substance into the medium that also sensitized the photoinduction of the polypeptide.
