Outline of Final Research Achievements |
We investigated changes of D-glutamate (D-Glu) content on reproduction in kuruma prawn Marsupenaeus japonicus. In the testis, content of D-Glu increased in seawater temperature rise or unilateral removal of eyestalk. In addition, the young male prawn contained large amounts of D-Glu in the genital tissue, and the activity of glutamate racemase, which catalyzes the interconversion of D- and L-Glu, was high in the testis. These data indicate that D-Glu biosynthesized actively in the stage.
