Taxonomic lineage

Bacteria › Proteobacteria › Alphaproteobacteria › Rickettsiales › Rickettsiaceae › Rickettsieae › Rickettsia › spotted fever group

Protein attributes

Sequence length	175 AA.
Sequence status	Complete.
Sequence processing	The displayed sequence is not processed.
Protein existence	Inferred from homology.

General annotation (Comments)

Function	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.
Catalytic activity	Formyl-L-methionyl peptide + H2O = formate + methionyl peptide. HAMAP MF_00163
Cofactor	Binds 1 Fe2+ ion By similarity.
Sequence similarities	Belongs to the polypeptide deformylase family.
