CRYSTAL STRUCTURE OF ZIPD FROM ESCHERICHIA COLI
Overview
The elaC gene product from Escherichia coli, ZiPD, is a 3' tRNA-processing, endonuclease belonging to the tRNase Z family of enzymes that have been, identified in a wide variety of organisms. In contrast to the elaC, homologue from Bacillus subtilis, E. coli elaC is not essential for, viability, and although both enzymes process only precursor tRNA, (pre-tRNA) lacking a CCA triplet at the 3' end in vitro, the physiological, role of ZiPD remains enigmatic because all pre-tRNA species in E. coli are, transcribed with the CCA triplet. We present the first crystal structure, of ZiPD determined by multiple anomalous diffraction at a resolution of, 2.9 A. This structure shares many features with the tRNase Z enzymes from, B. subtilis and Thermotoga maritima, but there are distinct differences ... [(full description)]
