title: Comparison of active sites of some microbial ribonucleases: structural basis for guanylic specificity.
abstract: Crystallographic studies of enzymes complexed with suitable ligands are an important tool to aid our understanding of biological catalysis. To this goal, a contribution is made by analysing structures of complexes formed by three guanyl-specific ribonucleases with guanosine 3'-monophosphate.
