Found in translation: CCA-adding enzymes reveal bacterialization of Asgard archaea prior to eukaryogenesis
CCA-adding enzymes are essential for transfer RNA (tRNA) maturation and translation among all domains of life.
CCA-adding enzymes are essential for transfer RNA (tRNA) maturation and translation among all domains of life. A long-standing dogma holds that archaea encode exclusively class one CCA-adding enzymes (CCA1), whereas bacteria and eukaryotes encode class two enzymes (CCA2),…
