Pseudouridine (Ψ-) specific reagents. (a) Pseudouridine and uridine reactivity with CMCT and similar water-soluble carbodiimides. Structural formula of CMCT is shown on the left. (b) Pseudouridine reactions with methylvinylsulfone and acrylonitrile. Pseudouridine residues are resistant to hydrazine, while unmodified uridines are specifically cleaved (see Figure 2(a)).
