This article reports experimental data related to the research article entitled "Poly(malic acid-co-l-lactide) as a Superb Degradation Accelerator for Poly(l-lactic acid) at Physiological Conditions" (H.T. Oyama, D. Tanishima, S. Maekawa, 2016) [1]. Hydrolytic degradation of poly(l-lactic acid) (PLLA) blends with poly(aspartic acid-co-l-lactide) (PAL) and poly(malic acid-co-l-lactide) (PML) oli...

Proteins and peptides are susceptible to a variety of chemical modifications that can affect their structure and biological functions. Among these modifications, the isomerization of aspartic acid and deamidation of asparagine occur in proteins and peptides during aging. The reaction proceeds spontaneously under physiological conditions through a five-membered succinimide ring intermediate form...

Two radioactive glycopeptides (Glycopeptides I and II) were isolated from the deoxycholate-soluble fraction of rat liver microsomes 90 min after injection of glucosamine-l-14C. These two glycopeptides were rich in mannose and N-acetylglucosamine but relatively poor in galactose and sialic acid. Glycopeptide I contained sialic acid, galactose, N-acetylglucosamine, mannose, aspartic acid, serine,...

L-Glutamic, L-aspartic acids and a number of their structural analogs, including quisqualic, kainic, ibotenic, quinolinic, and N-methyl-D-aspartic (NMDA) acids, increase inositol phospholipid hydrolysis when added to primary cultures of cerebellar granule cells, as is reflected by an enhanced formation of 3H-inositolmonophosphate (3H-IP1) in the presence of Li+. L-Glutamic acid also enhances th...

Bacteriol. 89:1521-1525. 1965.-The ability of Alcaligenes viscolactis to utilize amino acids in a basal salts solution (K(2)HPO(4), KH(2)PO(4), MgSO(4), MnSO(4), FeSO(4), NaCl) was studied. Of 27 amino acids, only l-asparag...

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...

A polypeptide of Mr 4400 was isolated from soybean (Glycine max) seeds by extraction with 60% ethanol followed by ion-exchange and reverse-phase chromatography. The peptide contains an unusually high amount of aspartic acid residues (approximately 25%, and hence is designated as soybean aspartic acid-rich peptide). Its complete primary structure was determined by conventional methods to be the ...

The kinetics of the reaction of L-aspartic acid (H3L +) with hydroxopentaaquarhodium (Ill) has been studied over the range 2.58:510[H3L 1 :5 12.90, 3.49 5.pH:5 4.3, 50°:5 t :565°C and 1=O.lmol dm-(NaCI04).The reaction takes place via an outer sphere association between RhOH+ and (H3L +) followed by transformation of the outer into an inner-sphere complex (chelate is formed) by slow interchange....

The aspartase overproducing mutant B-715 was used as a donor of the aspartase gene for further construction of the aspartase-hyperproducing strains by molecular cloning. In preliminary experiments activity of transformants and their efficiency in L-aspartic acid biosynthesis were compared. The conditions for recombinant strain multiplication, biomass activation and L-aspartic acid biosynthesis ...
