Escherichia coli ZiPD is the best characterized protein encoded by the elaC gene family and is a model for the 3'-pre-tRNA processing endoribonucleases (tRNase Z). A metal ligand-based sequence alignment of ZiPD with metallo-beta-lactamase domain proteins of known crystallographic structure identifies a ZiPD-specific sequence insertion of approximately 50 residues, which we will refer to as the ZiPD exosite. Functionally characterized ZiPD homologs from Bacillus subtilis, Methanococcus… CONTINUE READING
