Comments
Comments	Modifications were first compiled for E. coli [PUB_0045, PUB_0055, PUB_0056, PUB_0064, PUB_0065], and then modifications generated by homologous enzymes were mapped onto M. genitalium by sequence alignment. Modification reaction kinetics were compiled from the primary literature (See Note_RNAModification).
