Peptide deformylase (PDF) catalyzes the removal of the N-formyl group from the N-terminus of newly synthesized polypeptides; this process is crucial for cell survival. As it is an antibacterial drug target against Xanthomonas oryzae pv. oryzae (Xoo), PDF from Xoo was cloned, expressed, purified and crystallized. Native PDF crystals diffracted to 2.7 A resolution and belonged to the hexagonal space group P6(1)22, with unit-cell parameters a = b = 59.0, c = 266.3 A. One monomer is present in the asymmetric unit, with a corresponding crystal volume per protein weight of 3.50 A(3) Da(-1) and a solvent content of 64.9%.

Formylation facilitates the reduction of oxidized initiator methionines.

Within a cell, protein-bound methionines can be chemically or enzymatically oxidized, and subsequently reduced by methionine sulfoxide reductases (Msrs). Methionine oxidation can result in structural damage or be the basis of functional regulation of enzymes. In addition to participating in redox reactions, methionines play an important role as the initiator residue of translated proteins where they are commonly modified at their α-amine group by formylation or acetylation.
