Crystal structure of LIPDF

Structural highlights

1y6h is a 2 chain structure with sequence from "leptospira_icteroides"_noguchi_1919 "leptospira icteroides" noguchi 1919. This structure supersedes the now removed PDB entry 1rn5. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.

Function

[DEF_LEPIN] Removes the formyl group from the N-terminal Met of newly synthesized proteins. Requires at least a dipeptide for an efficient rate of reaction. N-terminal L-methionine is a prerequisite for activity but the enzyme has broad specificity at other positions (By similarity).[HAMAP-Rule:MF_00163]

Publication Abstract from PubMed

Peptide deformylase (PDF), which is essential for normal growth of bacteria but not for higher organisms, is explored as an attractive target for developing novel antibiotics. Here, we present the crystal structure of Leptospira interrogans PDF (LiPDF) at 2.2A resolution. To our knowledge, this is the first crystal structure of PDF associating in a stable dimer. The key loop (named the CD-loop: amino acid residues 66-76) near the active-site pocket adopts "closed" or "open" conformations in the two monomers forming the dimer. In the closed subunit, the CD-loop and residue Arg109 block the entry of the substrate-binding pocket, while the active-site pocket of the open subunit is occupied by the C-terminal tail from the neighbouring molecule. Moreover, a formate group, as one product of deformylisation, is observed bound with the active-site zinc ion. LiPDF displays significant structural differences in the C-terminal region compared to both type-I and type-II PDFs, suggesting a new family of PDFs.
