Identification
Name: Heme O
Description:HemeOo is a member of the chemical class known as Metalloporphyrins. These are polycyclic compounds containing a porphyrin moiety and a metal atom. Heme O (or haem O) differs from the closely related heme A by having a methyl group at ring position 8 instead of the formyl group. The isoprenoid chain at position 2 is the same. Heme O, found in the bacterium Pseudomonas aeruginosa, functions in a similar manner to heme A in mammalian oxygen reduction. (WikiPedia)
