metabolism
synthesis of RNA 2',3' cyclic phosphate ends via an ATP-dependent pathway comprising three nucleotidyl transfer steps: reaction of Rtc with ATP to form a covalent Rtc-(histidinyl-N)-AMP intermediate and release PPi, transfer of AMP from Rtc1 to an RNA 3'-phosphate to form an RNA(3')pp(5')A intermediate; and attack by the terminal nucleoside O2' on the 3'-phosphate to form an RNA 2',3' cyclic phosphate product and release AMP

synthesis of RNA 2',3'-cyclic phosphate ends via an ATP-dependent pathway comprising three nucleotidyl transfer steps: reaction of Rtc with ATP to form a covalent Rtc-(histidinyl-N)-AMP intermediate and release diphosphate, transfer of AMP from Rtc1 to an RNA 3'-phosphate to form an RNA(3')pp(5')A intermediate; and attack by the terminal nucleoside O2' on the 3'-phosphate to form an RNA 2',3'-cyclic phosphate product and release AMP
metabolism

RtcA might serve an end healing function in an RNA repair pathway, by converting RNA 2'-phosphates, which cannot be spliced by RtcB, to 2',3'-cyclic phosphates that can be sealed
