Sequence alignment of UlaGL/RNase Z homologs. Multiple sequence alignment of E. coli UlaG and homologous RNase Z sequences from selected Bacteria and Archea, with secondary structure overlaid above. Residues in contact with Mn2+ in E. coli UlaG are indicated with gray asterisks, and key histidine and aspartate residues in MBL conserved motifs I-V are marked with orange and purple asterisks, respectively.
