CC   -!- FUNCTION: Activates the tRNA-splicing ligase complex by facilitating
CC       the enzymatic turnover of catalytic subunit RtcB. Acts by promoting the
CC       guanylylation of RtcB, a key intermediate step in tRNA ligation. Can
CC       also alter the NTP specificity of RtcB such that ATP, dGTP or ITP is
CC       used efficiently (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the archease family. {ECO:0000255|HAMAP-
CC       Rule:MF_01222}.
