686237, 687282 |
1.3.98.3 | 4Fe-4S-center |
contains one [4Fe-4S]+ cluster per monomer |

1.3.98.3 | 4Fe-4S-center |
HemN binds a 4Fe-4S cluster through three cysteine residues: Cys-62, Cys-66 and Cys-69, a juxtaposed S-adenosyl-L-methionine coordinates the fourth Fe ion through its amide nitrogen and carboxylate oxygen, detailed binding mode, cofactor geometry required for Radical SAM catalysis |

1.3.98.3 | 4Fe-4S-center |
requirement, oxygen-sensitive Fe-S cluster, Cys-62, Cys-66 and Cys-69 are part of the conserved CXXXCXXC motif and essential for Fe-S cluster formation and enzyme function, Tyr-56 and His-58 are important for the Fe-S cluster integrity, His-58 may provide the fourth ligand besides the three cysteine residues |
656073 |
1.3.98.3 | 4Fe-4S-center |
structure, location and coordination of the cofactor, HemN requires the juxtaposition of the [4Fe-4S] cluster and the cosubstrate S-adenosyl-L-methionine |
