概要
- 論文の詳細を見る
Enzymes associated with nitrogen metabolism were determined in the gill, liver and muscle tissues of Periophthalmus chrysospilos. Glutamate dehydrogenase, alanine transaminase and aspartate transaminase were detected in all tissues studied. A complete purine nucleotide cycle was not present. Glutamine synthetase was not detectable, suggesting that this enzyme was not responsible for detoxification of intra-mitochondrially generated ammonia. Glutamine was the most effective substrate for in vitro ammoniagenesis in the isolated muscle mitochondria. The possible role of glutamate dehydrogenase in mitochondrial ammoniagenesis in this mudskipper is discussed.
