tRNA 3'-processing endoribonuclease (tRNase Z) is one of the enzymes, involved in the 3'-end processing of precursor tRNAs and is a member of, the metallo-beta-lactamase superfamily. tRNase Z crystal structures have, revealed that the enzyme forms a dimer and has a characteristic domain, named a flexible arm or an exosite, which protrudes from the, metallo-beta-lactamase core and is involved in tRNA binding. The refined, structure of Thermotoga maritima tRNase Z has been determined at 1.97 A, resolution, revealing the structure of the flexible arm and the zinc-bound, active site. The structure of the flexible arm of T. maritima tRNase Z is, distinct from those of the Bacillus subtilis and Escherichia coli tRNase, Zs. A comparison of the three tRNase Z structures revealed differences in, the dimer orientation, which may be related to the unique cleavage-site, specificity of T. maritima tRNase Z.
