Environmental Heme Utilization by Heme-Auxotrophic Bacteria [PDF]
, 2012 Heme, an iron-containing porphyrin, is the prosthetic group for numerous key cellular enzymatic and regulatory processes. Many bacteria encode the biosynthetic enzymes needed for autonomous heme production. Remarkably, however, numerous other bacteria lack a complete heme biosynthesis pathway, yet encode heme-requiring functions.

Heme‐hemopexin: A ‘Chronosteric’ heme‐protein [PDF]
IUBMB Life, 2007 AbstractHemopexin (HPX) serves as scavenger and transporter of toxic plasma heme to the liver. HPX is formed by two four‐bladed β‐propeller domains, resembling two thick disks that lock together at a 90° angle. The heme is bound between the two β‐propeller domains in a pocket formed by the interdomain linker peptide.
