A black and white photo of the front of an old cinder block building with a large CLOSED sign on a glass front door.  There are two old fold out chairs sitting next to the door and a plate glass window to the right of those.

Closed I guess?

A pretty protein structure made mostly of beta-sheets. There are two hemes, one per monomer. In P460, the heme is linked to a lysine residue and can do hydroxylamine oxidation. In one c prime beta, the heme has peroxidase-like activity. In another,it does gas binding.

I'm particularly interested in how these properties in cytochromes P460 are affected by the unusual heme-protein crosslinking. This makes them green, distorts the heme and allows them to oxidise the iron-bound NH2OH to N2O, a greenhouse gas. This is basically what makes them #P460 instead of #P450!
