We previously showed copious amounts of free d-glutamate, a novel d-amino acid, in the tissue of the male reproductive organs of Marsupenaeus japonicus. Herein, we clarified the distribution and potential role of d-glutamate and d-alanine in male reproductive tissues, namely the testis, vas deferens and seminal receptacle at different growth stages of M. japonicus. The percentage of d-glutamate to total glutamate was over 50% in these tissues. In particular, the content of d-glutamate was the most abundant in the vas deferens, the ratio of d-glutamate to total glutamate was approximately 80%. In contrast, d-alanine content was the lowest in the vas deferens among these tissues. d-Glutamate content was the highest when the prawn weighed 12\u00a0g, indicating that d-glutamate is actively synthesized in the younger stage. Our findings suggest that d-glutamate plays an important role in the reproductive functions of M. japonicus.<\/jats:p>","DOI":"10.1093\/jb\/mvad072","type":"journal-article","created":{"date-parts":[[2023,10,3]],"date-time":"2023-10-03T17:09:55Z","timestamp":1696352995000},"page":"95-100","source":"Crossref","is-referenced-by-count":3,"title":["Distribution and role of <scp>d<\/scp>-glutamate, a novel <scp>d<\/scp>-amino acid identified in animals, in the reproductive tissues of male kuruma prawn <i>Marsupenaeus japonicus<\/i>"],"prefix":"10.1093","volume":"175","author":[{"given":"Naoko","family":"Yoshikawa","sequence":"first","affiliation":[{"name":"Shizuoka Institute of Science and Technology Department of Materials and Life Science, Faculty of Science and Technology, , Fukuroi, Shizuoka 437-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Natsuki","family":"Yoshitomi","sequence":"additional","affiliation":[{"name":"Shizuoka Institute of Science and Technology Department of Materials and Life Science, Faculty of Science and Technology, , Fukuroi, Shizuoka 437-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuki","family":"Nakada","sequence":"additional","affiliation":[{"name":"Shizuoka Institute of Science and Technology Department of Materials and Life Science, Faculty of Science and Technology, , Fukuroi, Shizuoka 437-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naomi","family":"Sawada","sequence":"additional","affiliation":[{"name":"Shizuoka Institute of Science and Technology Department of Materials and Life Science, Faculty of Science and Technology, , Fukuroi, Shizuoka 437-8555, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,10,3]]},"reference":[{"key":"2024011001022397500_ref1","doi-asserted-by":"crossref","first-page":"49","DOI":"10.15583\/jpchrom.2014.005","article-title":"Enantioselective two-dimensional high-performance liquid chromatographic determination of amino acids; analysis and physiological significance of d-amino acids in mammals","volume":"35","author":"Miyoshi","year":"2014","journal-title":"Chromatography"},{"key":"2024011001022397500_ref2","first-page":"319","article-title":"Presence of d-alanine in crustacean muscle and hepatopancreas","volume":"66","author":"D\u2019Aniello","year":"1980","journal-title":"Comp.
