Aminoacyl-tRNA synthetases are essential enzymes that catalyze attachment of amino acids to tRNAs for decoding of genetic information. In higher eukaryotes, several synthetases associate with non-synthetase proteins to form a high-molecular mass comp

Accurate aminoacylation of tRNAs by aminoacyl-tRNA synthetase is essential for the fidelity of protein synthesis. For Methanococcus jannaschii tRNA Pro , accuracy is difficult because the cognate prolyl-tRNA synthetase also recognizes and aminoacylat

The core of Escherichia coli tRNA Cys is important for aminoacylation of the tRNA by cysteine-tRNA synthetase. This core differs from the common tRNA core by having a G15:G48, rather than a G15:C48 base-pair. Substitution of G15:G48 with G15:C48 decr

Synthesis of cysteinyl-tRNA(Cys) by cysteine-tRNA synthetase is required for decoding cysteine codons in all known organisms. The genome of the archaeon Methanococcus jannaschii lacks the gene for a normal cysteine-tRNA synthetase. The activity of th

The position of the tertiary Levitt pair between nucleotides 15 and 48 in the transfer RNA core region suggests a key role in stabilizing the joining of the two helical domains, and in maintaining the relative orientations of the D and variable loops

The conformation of a tRNA in its initial contact with its cognate aminoacyl-tRNA synthetase was investigated with the Escherichia coli glutamyl-tRNA synthetase-tRNA(Glu) complex. Covalent complexes between the periodate-oxidized tRNA(Glu) and its sy

The core region of Escherichia coli tRNA(Cys)is important for aminoacylation of the tRNA. This core contains an unusual G15:G48 base pair, and three adenosine nucleotides A13, A22 and A46 that are likely to form a 46:[13:22] adenosine base triple. We

The complete genomic sequencing of Methanococcus jannaschii cannot identify the gene for the cysteine-specific member of aminoacyl-tRNA synthetases. However, we show here that enzyme activity is present in the cell lysate of M. jannaschii . The demon

The CCA end is common to all tRNAs as the universal site for amino acid attachment+ It is also conserved in the 39-terminal tRNA-like structure of viral genomes that can be aminoacylated by an aminoacyl-tRNA synthetase (Florentz & Giege, 1995)+ Durin

The folate chromophore in native Escherichia coli DNA photolyase ([6R]-5,10-CH+-H4Pte(Glu)n=3-6) serves as an antenna, transferring light energy to the fully reduced flavin (FADH2) reaction center at high efficiency (EET = 0.92). Apophotolyase recons
