Structures of the Noncanonical RNA Ligase RtcB Reveal the Mechanism of Histidine Guanylylation

RtcB is an atypical RNA ligase that joins either 2′,3′-cyclic phosphate or 3′-phosphate termini to 5′-hydroxyl termini. In contrast to typical RNA ligases, which rely on ATP and Mg(II), catalysis by RtcB is dependent on GTP and Mn(II) with ligation proceeding through a covalent RtcB–histidine–GMP in...
