The sequential 2′,3′-cyclic phosphodiesterase and 3′-phosphate/5′-OH ligation steps of the RtcB RNA splicing pathway are GTP-dependent
The RNA ligase RtcB splices broken RNAs with 5′-OH and either 2′,3′-cyclic phosphate or 3′-phosphate ends. The 3′-phosphate ligase activity requires GTP and entails the formation of covalent RtcB-(histidinyl)-GMP and polynucleotide-(3′)pp(5′)G intermediates. There are currently two models for how Rt...
