Comments

| case <FTTag:act_site> and <FTGroup:1> | |
| 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. |
| CATALYTIC ACTIVITY | Reaction=N-terminal N-formyl-L-methionyl-[peptide] + H2O = N-terminal L-methionyl-[peptide] + formate; Xref=Rhea:RHEA:24420, Rhea:RHEA- COMP:10639, Rhea:RHEA-COMP:10640, ChEBI:CHEBI:15377, ChEBI:CHEBI:15740, ChEBI:CHEBI:49298, ChEBI:CHEBI:64731; EC=3.5.1.88; |
| end case | |
| case <FTGroup:1> | |
| COFACTOR | Name=Fe(2+); Xref=ChEBI:CHEBI:29033; Note=Binds 1 Fe(2+) ion.; |
| end case | |
| SIMILARITY | Belongs to the polypeptide deformylase family. |
