Common NameHeme D
DescriptionHeme D is a member of the chemical class known as tetrapyrroles and Derivatives. These are polycyclic aromatic compounds containing four pyrrole rings joined by one-carbon units linking position 2 of one pyrrole ring to position 5 of the next. (inferred from compound structure). A heme (American English) or haem (British English) is a prosthetic group that consists of an iron atom contained in the center of a large heterocyclic organic ring called a porphyrin. Heme D is a derivative of heme B, but in which the propionic acid side chain at the carbon of position 6, which is also hydroxylated, forms a γ-spirolactone. Ring III is also hydroxylated at position 5, in a conformation trans to the new lactone group. Heme D is the site for oxygen reduction to water of many types of bacteria at low oxygen tension. In E coli, heme D is formed from protoheme in the interior of the catalase hydroperoxidase II (HPII) molecule through a self-catalyzed reaction. [PMID: 8621527 ]
