iron from heme without tetrapyrrol degradation, a novel enzymatic reaction corresponding to the deferrochelation of the heme. YfeX and EfeB are the sole proteins that can provide heme iron to E. coli K12. YfeX and EfeB are capable of extracting iron from heme while preserving the protoporphyrin ring
