Metabolism of L-aspartic acid.
Aspartic acid, like glutamic acid, occupies a central position in amino acid metabolism. In most tissues it takes part in the transamination reaction (1). In the liver and the kidney, where all amino acids undergo cleamination, the rate of this process for aspartic acid is second only to glutamic acid (2). For these reasons, one would expect the exchange of amino nitrogen of aspartic acid with ...
متن کاملThe Synthesis of Aspartic Acid
No one of the methods proposed for the synthesis of aspartic acid is entirely satisfactory as a practical procedure. The synthesis, described in a recent paper (1) from this laboratory, has been utilized in preparing 50 to 60 gm. lots of recrystallized aspartic acid but even here the beginning reagents are expensive, the over-all yield is only about 30 per cent of the theoretical, and the proce...
متن کاملOxovanadium(IV) complexes of salicyl-L-aspartic acid and salicylglycyl-L-aspartic acid.
The dipeptide and tripeptide analogues salicyl-L-aspartic acid (Sal-L-Asp) and salicylglycyl-L-aspartic acid (SalGly-L-Asp) were synthesized and their protonation and complex formation with V(IV)O2+ were studied in aqueous solution through the use of pH-potentiometry and spectroscopic (UV-Vis, CD and EPR) techniques. The phenolate terminus proved to be a good anchoring site to promote (i) the m...
متن کاملGlutamic acid inhibition of aspartic acid utilization in threonine biosynthesis.
The observation that Leuconostoc dextranicum 8086 requires either aspartic acid or threonine for growth resulted in studies in which a ri%e’ of aspartic acid in the biosynthesis of threonine was demonstrated in certain lactobacilli (1). In the present investigation, the nature of the requirement for either aspartic acid or threonine for growth of L. dextranicum 8086 has been found to be the res...
متن کاملEnzymatic conversion of formylaspartic acid to aspartic acid.
In previous investigations imidazoleacetic acid was shown to be quantitatively converted to formylaspartic acid by a partially purified enzyme preparation obtained from Pseudomonas sp. that requires DPNH’ and oxygen (2, 3). An intermediate in this process was isolated from the incubation mixture with highly purified enzyme preparations and was characterized as N-formimino-L-aspartic acid (4). E...
