CA   (1) 5 AH2 + 2 H(+) + heme b + 4 O2 = 5 A + delta-staphylobilin + Fe(2+) +
CA   formaldehyde + 4 H2O.
CA   (2) 5 AH2 + 2 H(+) + heme b + 4 O2 = 5 A + beta-staphylobilin + Fe(2+) +
CA   formaldehyde + 4 H2O.
CC   -!- This enzyme, which is found in some pathogenic bacteria, is involved
CC       in an iron acquisition system that catabolizes the host's hemoglobin.
CC   -!- The two enzymes from the bacterium Staphylococcus aureus, encoded by
CC       the isdG and isdI genes, produce 67.5 % and 56.2 % delta-
CC       staphylobilin, respectively.
