| Outline of Final Research Achievements |
D-Glutamate was specifically detected in male genital tissue of kuruma prawn Marsupenaeus japonicus. To reveal the physiological functions of D-glutamate, the distribution of D-glutamate was examined on these tissues of the prawn. D-Glutamate was found in the testis, vas deferens, and male genital aperture, respectively. The ratio of D-glutamate to total glutamate was over 80% in vas deferens. Moreover, the activity of glutamate racemase which catalyzes the interconversion of D- and L-glutamate was detected in these tissues. Thus, D-glutamate in the prawn is biosynthesized by glutamate racemase.
