PEPTIDE DEFORMYLASE
Overview
Protein synthesis in bacteria involves the formylation and deformylation, of the N-terminal methionine. As eukaryotic organisms differ in their, protein biosynthetic mechanisms, peptide deformylase, the bacterial enzyme, responsible for deformylation, represents a potential target for, antibiotic studies. Here we report the crystallization and 2.9 A X-ray, structure solution of the zinc containing Escherichia coli peptide, deformylase. While the primary sequence, tertiary structure, and use of, coordinated cysteine suggest that E. coli deformylase belongs to a new, subfamily of metalloproteases, the environment around the metal appears to, have strong geometric similarity to the active sites of the thermolysin, family. This suggests a possible similarity in their hydrolytic, mechanisms. ... [(full description)]
