Common Nameharderoheme III
Descriptionharderoheme III is a heme metabolite belonging to the class of porphyrins. Its chemical structure features a central iron atom coordinated by a porphyrin ring, which is crucial for its reactivity and interactions in various biochemical pathways. harderoheme III is generated through the reaction of ChdCs with chlorite, leading to the formation of heme b as well (PMID:40132279 ). In enzymatic processes, the decarboxylation of precursor molecules is a key step, where harderoheme III acts as an intermediate. Specifically, after the decarboxylation of P2, harderoheme III is suggested to rebind or rotate within the active site, allowing for further decarboxylation mediated by Tyr144 (PMID:34382397 ). Additionally, molecular dynamics simulations reveal that Lys149 plays a critical role in stabilizing harderoheme III and positioning it for subsequent reactions at the catalytic site (PMID:32638770 ). Furthermore, studies indicate that the use of harderoheme III as a substrate or substitutions of redox-active side chains do not significantly alter the radical spectrum dynamics during reactions with H2O2 (PMID:29414780 ).
