Figure 1: Stop-codon specificity of RF1 and RF2 in termination. Earlier hypotheses have ascribed the dual second-position specificity of RF2 to the ability of Ser 193 to form bifurcated hydrogen bonds ...

Living things, from bacteria to humans, depend on a workforce of proteins to carry out essential tasks within their cells. Proteins are chains of amino acids that are strung together according to ...
