Crystal structure of Peptide Deformylase 2 with actinonin from Bacillus cereus

Overview

Peptide deformylase (PDF) is a metalloenzyme that removes the N-terminal, formyl groups from newly synthesized proteins. It is essential for, bacterial survival, and is therefore-considered as a potential target for, antimicrobial chemotherapy. However, some bacteria including medically, relevant pathogens possess two or more def-like genes. Here we have, examined two PDFs from Bacillus cereus. The two share only 32% sequence, identity and the crystal structures show overall similarity with PDF2, having a longer C-terminus. However, there are differences at the two, active sites, and these differences appear to contribute to the activity, difference seen between the two. BcPDF2 is found as a dimer in the crystal, form with two additional actinonin bound at that interface.
