The 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 کاملCrystal Structure of Reovirus Attachment Protein σ1 in Complex with Sialylated Oligosaccharides
Many viruses attach to target cells by binding to cell-surface glycans. To gain a better understanding of strategies used by viruses to engage carbohydrate receptors, we determined the crystal structures of reovirus attachment protein σ1 in complex with α-2,3-sialyllactose, α-2,6-sialyllactose, and α-2,8-di-siallylactose. All three oligosaccharides terminate in sialic acid, which serves as a re...
متن کاملStructure of Reovirus σ1 in Complex with Its Receptor Junctional Adhesion Molecule-A
Viral attachment to specific host receptors is the first step in viral infection and serves an essential function in the selection of target cells. Mammalian reoviruses are highly useful experimental models for studies of viral pathogenesis and show promise as vectors for oncolytics and vaccines. Reoviruses engage cells by binding to carbohydrates and the immunoglobulin superfamily member, junc...
متن کاملMetabolism 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 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...
