The d-amino acid content of Ishizuchi-kurocha, a post-fermented tea produced in Ehime, Japan, was measured. Ishizuchi-kurocha mainly contains d-glutamic and d-alanine, but it also small amount d-aspartic acid. Two types lactic bacteria, Lactiplantibacillus plantarum (L. plantarum) Levilactobacillus brevis brevis), are the main species involved fermentation during process. Therefore, acid-produc...

We hypothesized that administration of estradiol benzoate to males and testosterone propionate to female neonatal rat pups alters sex-specific ventilatory responses to aspartic acid with correspondent changes in N-methyl-D-aspartate receptor subunit 1 (NR1) expression determined by Western blot in specific brain regions. One-day-old rat pups received estradiol benzoate, testosterone propionate,...

15 Roberts, R. B., P. H. Abelson, D. B. Cowie, E. T. Bolton, and R. J. Britten, Carnegie Institution of Washington Publication 607, Washington, D. C. (1955). 16 The rather low values for threonine and lysine obtained with both labeled aspartic acids in Lemna probably are significant and may indicate a "channeling" of aspartic acid, i.e., a preferential utilization of aspartic acid for incorpora...

By determining the extent of racemization of aspartic acid in a well-dated bone, it is possible to calculate the in situ first-order rate constant for the interconversion of the L and D enantiomers of aspartic acid. Collagen-based radiocarbon-dated bones are shown to be suitable samples for use in "calibrating" the racemization reaction. Once the aspartic-acid racemization reaction has been "ca...

Strong evidence indicates that virions of mammalian reoviruses undergo proteolytic processing by acid-dependent cellular proteinases as an essential step in productive infection. Proteolytic processing takes the form of a series of cleavages of outer-capsid proteins final sigma3 and mu1/mu1C. Previous studies showed an effect of both NH4Cl and E-64 on these cleavages, indicating that one or mor...

The metabolic pathway for the synthesis of guanidinosuccinic acid was studied in the rat. Labeled guanidinosuccinic acid was isolated from the urine of animals given L-[guanidino-14C]arginine intraperitoneally but did not appear in the urine after administration of D,L-[guanidino-14C]canavanine. Radioactive arginine and nonradioactive aspartic acid and arginine were infused in the isolated, per...

Subcutaneous administration of aspartic acid results in a long-lasting but reversible depression of ventilation in male but not in female rats. Aspartic acid acts on N-methyl-D-aspartate receptors. The present study tested the hypothesis that a noncompetitive N-methyl-D-aspartate-receptor antagonist, dextromethorphan (Dex), would depress ventilation in female rats and stimulate it in male rats....

In biotin deficiency, aspartic acid becomes a limiting factor in the growth of Streptococcus faecalis ATCC 9190. Suboptimal concentrations of L-aspartate in biotin-deficient medium produce partial growth followed by lysis, which is typical of cell wall lysis due to depletion of an amino acid essential for cell wall biosynthesis. D-Aspartate, which is utilized by the cells with considerable less...
