That isopenicillin synthase uses oxygen that binds to this.
One form of this element is usually coordinated with two His and one Asp or Glu protein residues in enzymes that either require an alpha-keta acid as cosubstrate, or degrade aromatic molecules and catalyze oxidative ring cleavage. The synthesis of a precursor to penicillin is catalyzed by an enzyme of the oxidoreductase family and its active site contains this element. That isopenicillin synthase uses oxygen that binds to this. A protein that regulates this metal in humans is rich in beta sheets and HAMP, and is the gene that encodes that protein, which is generally 25 amino acids long. In addition to being regulated by hepcidin, this metal is found with sulfur in proteins such as cytochrome c, which are found in the electron transport chain of the mitochondria. FTP, name this element that is found in the center of a porphyrin ring in heme.
