Figure 6-54Structure of a tRNA-splicing endonuclease docked to a precursor tRNA

The endonuclease (a four-subunit enzyme) removes the tRNA intron (blue). A second enzyme, a multifunctional tRNA ligase (not shown), then joins the two tRNA halves together. (Courtesy of Hong Li, Christopher Trotta, and John Abelson.)
