Cysteine is ligated to tRNA(Cys) by cysteinyl-tRNA synthetase in most organisms. However, in methanogenic archaea lacking cysteinyl-tRNA synthetase, O-phosphoserine is ligated to tRNA(Cys) by O-phosphoseryl-tRNA synthetase (SepRS), and the phosphoseryl-tRNA(Cys) is converted to cysteinyl-tRNA(Cys) ...
