The hydroxylamine oxidoreductase (HAO) family consists of octaheme proteins that harbor seven bis-His ligated electron-transferring hemes and one 5-coordinate catalytic heme with His axial ligation. Oxidative HAOs have a homotrimeric configuration with the monomers covalently attached to each other via a unique double crosslink between a Tyr residue and the catalytic heme moiety of an adjacent subunit. This crosslinked active site heme, termed the P460 cofactor, has been hypothesized to modulate enzyme reactivity towards oxidative cata
