WebThe binding site for substrates is the distal axial position of heme group 1. The three amino acid residues in a distance that permits interaction with substrates are Arg 114, Tyr 218, and His 276. The active site is completed by a conserved calcium ion, the exact role of which remains unclear. WebThe substrates on which enzymes act usually have molecular weights of several hundred. Because of the difference in size between the two, only a fraction of the enzyme is in …
