摘要：

This chapter reviews what is known about the mechanism of precursor tRNA splicing: (i) the tRNA substrates for the splicing reaction, (ii) the enzymes involved in removing the introns to form the mature tRNA, (iii) interactions between these enzymes and their tRNA substrates and cofactors, (iv) the organization of tRNA splicing in the nucleus, (v) the identity of splicing mutants that affect the enzymatic machinery, (vi) current knowledge about the differences and similarities of tRNA splicing in systems of various organisms, and (vii) the possible function of tRNA introns.
