General annotation (Comments)

Function	Removes the formyl group from the N-terminal Met of newly synthesized proteins. Ref.1
Catalytic activity	Formyl-L-methionyl peptide + H2O = formate + methionyl peptide.
Cofactor	Binds 1 Zinc ion per subunit. Ref.6
Enzyme regulation	Inhibited by actinonin. Ref.5 Ref.6
Subunit structure	Homodimer. Ref.8
Subcellular location	Plastid › chloroplast stroma. Mitochondrion. Note: Reported by Ref.1 to be localized to mitochondria based on transient expression in an heterologous system. Ref.1 Ref.5
Tissue specificity	Expressed in roots, leaves, flowers and siliques. Ref.1
Disruption phenotype	No visible phenotype. Ref.7
Sequence similarities	Belongs to the polypeptide deformylase family.
Biophysicochemical properties	Kinetic parameters: KM=240 µM for N-formyl-Met-Leu-rho-nitroanilide Ref.5 KM=710 µM for N-formyl-Met-Ala-Ser Vmax=0.11 µmol/min/mg enzyme toward N-formyl-Met-Leu-rho-nitroanilide Vmax=0.20 µmol/min/mg enzyme toward N-formyl-Met-Ala-Ser
Sequence caution	The sequence AAD39667.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended. The sequence AAK32873.1 differs from that shown. Reason: Erroneous initiation. Translation N-terminally extended.
