Aspartase (L-aspartate ammonia lyase, EC 4.3.1.1) catalyses the reversible amination and deamination of L-aspartic acid to fumaric acid which can be used to produce important biochemical. In this study, we have explored the characteristics of aspartase from Pseudomonas aeruginosa PAO1 (PA-AspA).

Abstract Reaction of L-aspartic acid with excess of bis(trimethylsilyl)amine under reflux provides optically pure L-aspartic acid bis(trimethylsilyl) ester in quantitative yield. This silyl ester reacts with a variety of acylating reagens in tetrahydrofuran to give N-protected aspartic acids and dipeptides in good yields without racemization.

The Acidulant Properties of L‐aspartic Acid
Journal of Food Science, 1965SUMMARY Preliminary studies suggest L‐aspartic acid possesses acidulant properties of potential use in foods. Present costs are not competitive with citric acid, though special application may exist. The concept of using amino acids as flavoring materials is suggested, with a second role in improving nutritional quality.

Active transport of l-aspartic acid in Neurospora crassa
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1971Abstract Transport of l -aspartic acid in Neurospora crassa conidia is shown to be mediated by neutral and general amino acid transport systems. The transport activity is dependent on pH and results in accumulation of l -aspartic acid against a gradient. Mutants deficient in transport of l -aspartic acid are described.

Thermodynamics of the conversion of aqueous l-aspartic acid to fumaric acid and ammonia
Biophysical Chemistry, 1986The thermodynamics of the conversion of aqueous L-aspartic acid to fumaric acid and ammonia have been investigated using both heat conduction microcalorimetry and high-pressure liquid chromatography. The reaction was carried out in aqueous phosphate buffer over the pH range 7.25-7.43, the temperature range 13-43 degrees C, and at ionic strengths ...

Polyene macrolide amphotericin B (AmB) is the drug of choice for the treatment of disseminated fungal infections. However, because of its pronounced side effects, the drug has limited applicability. There are few interesting reports, which state that co-administration of the drug with homo-peptide of polyaspartic acid reduces the side effects of the ...
