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 ...
The genetic code is not frozen. Genetic code variations found in microorganisms include codon bias, codon reassignment, ambiguous decoding and natural genetic code expansion. Codon bias, which is ...
The encoding of two non-universal amino acids involves dynamic redefinition of 'stop' signals in the genetic code. Bacteria with multiple proteins containing these amino acids add to our appreciation ...
