    Different microbial species are thought to occupy distinct ecological niches, subjecting each species to unique selective constraints, which may leave a recognizable signal in their genomes. Thus, it may be possible to extract insight into the genetic basis of ecological differences among...

    Peptide synthesis in eukaryotes terminates when eukaryotic release factor 1 (eRF1) binds to an mRNA stop codon and occupies the ribosomal A site. Domain 1 of the eRF1 protein has been implicated in stop codon recognition in a number of experimental studies. In order to further pinpoint the...

    Threonine uptake in Escherichia coli wild-type and in threonine-producing strains decreased throughout threonine production. In contrast to previously published results, the SstT uptake system is not the sole serine/threonine permease in E. coli, since a novel transport system was detected in an...

  • amino acid.  // Taber's Cyclopedic Medical Dictionary (2009);2009, Issue 21, p95 

    An encyclopedia entry for amino acids is presented. Amino acids are a group of organic compounds with both an amino group and a carboxyl group. They are building blocks of proteins. Essential and non-essential amino acids are two types of these compounds. Essential amino acids include histidine,...

  • Identifying sites under positive selection with uncertain parameter estimates. Aris-Brosou, Stéphane // Genome;Jul2006, Vol. 49 Issue 7, p767 

    Codon-based substitution models are routinely used to measure selective pressures acting on protein-coding genes. To this effect, the nonsynonymous to synonymous rate ratio (dN/dS = ω) is estimated. The proportion of amino-acid sites potentially under positive selection, as indicated by...
