Structure, and consequently properties, of ionic liquids can be easily tailored by changing cation/anion combinations and/or attaching functional groups. By grafting enantiopure moieties to the framework liquid it is possible prepare bioinspired chiral molecules that serve as a reaction medium, additive or even asymmetric catalyst. In this context, new (CILs), based on biomolecules, such aminoa...

and is shown as the viral-complementary strand. The upstream non-coding sequence comprises 81 nucleotides, and the open reading frame codes for the N polypeptide, deduced to be 564 aminoacids long (mol. wt. 63,033 Da). Nucleotide and aminoacid sequences exhibit varying degrees of identity when compared to homologous regions of other arenavirus sequences. The comparison with Tacaribe virus (2), ...

A general strategy is described for finding which amino acid sequences have native states in a desired conformation (inverse design). The approach is used to design sequences of 48 hydrophobic and polar aminoacids on threedimensional lattice structures. Previous studies employing a sequence-space Monte-Carlo technique resulted in the successful design of one sequence in ten attempts. The presen...

In addition to the full length mRNA activated human peripheral blood mononuclear cells (PBMC) and T cell tumor lines express several alternatively spliced Fas variants. At least five of these code for soluble Fas (CD95) molecules. In vitro studies suggest that these soluble Fas isoforms inhibit apoptosis induced by agonistic antibodies and, more importantly, by the natural Fas ligand in Fas-bea...

Amino acids are one of the most necessary substances in intracellular metabolic processes.aromatic aminoacids such as phenylalanine and tyrosine are precursor of melanin so are important materials for the skin pigmentation.metabolic disorders in the melanin synthesis causes milky macules on the skin of patients,known as vitiligo.these patients are hypersensitive to sunlight and consequently at ...
