Identification of the modified cytidine C*. (A) Accurate mass analysis of CID-MS/MS fragments of the base ion of C* (measured m/z 224.1617; expected m/z 224.1618). m/z 207.1352 and m/z 165.1135 are consistent with the loss of NH3 and CH5N3, respectively, from the base ion of C*. (B) MS fragmentation pattern of an agmatine standard. m/z 114.1 and m/z 72.1 are consistent with the loss of NH3 and CH5N3, respectively, from agmatine.
