ATP-dependent DNA ligases are found in all eukaryotic species. Mammalian cells contain four DNA ligase isozymes. Amino acid-sequence comparisons suggest that a core catalytic domain common to all ...

RNA breaks destined for repair are inflicted by sequence-specific or structure-specific endoribonucleases ... in diverse taxa in all phylogenetic domains of life. ATP-dependent RNA ligases join 3’-OH ...

By this means, the genetic code of the genome is translated into the amino acid sequence of proteins ... a special E3 ligase that joins a small protein modification called UFM1 to the large ...

C-terminal amidation is a PTM that involves the addition of an amid group to the C-terminus of a peptide or protein. Currently there is no direct evidence to suggest that C-terminal amidation of ...
