Indigenous amino acids in primitive CR meteorites [PDF]

arXiv, 2008
CR meteorites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites, two of which show the highest amino acid concentrations ever found in a chondrite. EET92042, GRA95229 and GRO95577 were analyzed for their amino acid content using high performance liquid chromatography with ...

Candidate amino acids involved in H+ gating of acid-sensing ion channel 1a [PDF]

, 2008
Acid-sensing ion channels are ligand-gated cation channels, gated by extracellular H+. H+ is the simplest ligand possible, and whereas for larger ligands that gate ion channels complex binding sites in the three-dimensional structure of the proteins have

Impact contribution of prebiotic reactants to Earth [PDF]

It is proposed that the AIB amino acid at the K/T boundary were synthesized during entry of a comet. However, whether they were synthesized or supplied directly from space, the concentration of amino acids in the shallow K/T sea would have been about 10 ...

The d-amino acid oxidase of Neurospora [PDF]

, 1944
Among artificially produced mutants of the mold Neurospora have been found strains lacking the ability to synthesize specific amino acids (1, 2). In the course of biochemical and genetic studies of this group of mutants it was observed that some of the ...

The Triplet Genetic Code had a Doublet Predecessor

, 2004
Information theoretic analysis of genetic languages indicates that the naturally occurring 20 amino acids and the triplet genetic code arose by duplication of 10 amino acids of class-II and a doublet genetic code having codons NNY and anticodons ...
