| Research Abstract |
Toyo'oka applied a method a method he developed to the determination of D, L-amino acids in food and biosamples. Nagata isolated D-alanine dehydrogenase from Pyrobaculum islandicum. Misono cloned glutamate racemase and determined the sequence of the enzyme. Asano cloned D-amino acid amide specific amidase from O. anthropi and investigated its relation to the function. Esaki analyzed the gene of amino acid rasemase obtained from Saccharomyces cerevisiae and Schizosaccharomyces pombe. Horiike demonstrated a reverse localization of D-serine and D-amino acid oxidase in the mammals brain. Ymada suggested that a membrane dipeptidase might be useful for the diagnosis of kidney disease. Hashimoto suggested a probable uptake of D-serine into a cell by a stimulation of depolarization. Nishikawa proposed a possible binding of endogenous D-serine with an another site in addition to NMDA glycine binding site. Imai demonstrated the emergence of glutamate transporter at the same site of existence of endogenous D-aspartate. Kagawa isolated a specific degradation enzyme of a D-aspartate containing peptide. Iwatsubo Identified an essential functional domain of presenilin as the most C-terminal amino acid for the enhancement of A β 42 production. Fujii proposed a stereospecific structure for the reverse reaction of aspartate in α A-chrystallin.
