'''PEPTIDE DEFORMYLASE'''<br />


==Overview==
==PEPTIDE DEFORMYLASE==
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. ... [[http://ispc.weizmann.ac.il/pmbin/getpm?9374869 (full description)]]

Structural highlights

1dff is a 1 chain structure with sequence from Escherichia coli. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Method:X-ray diffraction, Resolution 2.88Å
Ligands:
Resources:FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

DEF_ECOLI 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.[HAMAP-Rule:MF_00163]

Evolutionary Conservation

Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf.
