CRYSTAL STRUCTURE OF HEMOPROTEIN DOMAIN OF P450BM-3, A PROTOTYPE FOR MICROSOMAL P450'S

Structural highlights

2hpd is a 2 chain structure with sequence from Atcc 14581. Full crystallographic information is available from OCA. For a guided tour on the structure components use FirstGlance.
Ligands:
Activity:	Unspecific monooxygenase, with EC number 1.14.14.1
Resources:	FirstGlance, OCA, PDBe, RCSB, PDBsum, ProSAT

Function

[CPXB_BACME] Functions as a fatty acid monooxygenase. Catalyzes hydroxylation of medium and long-chain fatty acids at omega-1, omega-2 and omega-3 positions, with optimum chain lengths of 12-16 carbons (lauric, myristic, and palmitic acids). The reductase domain is required for electron transfer from NADP to cytochrome P450.

Publication Abstract from PubMed

Cytochrome P450BM-3, a bacterial fatty acid monoxygenase, resembles the eukaryotic microsomal P450's and their flavoprotein reductase in primary structure and function. The three-dimensional structure of the hemoprotein domain of P450BM-3 was determined by x-ray diffraction and refined to an R factor of 16.9 percent at 2.0 angstrom resolution. The structure consists of an alph and a beta domain. The active site heme is accessible through a long hydrophobic channel formed primarily by the beta domain and the B' and F helices of the alpha domain. The two molecules in the asymmetric unit differ in conformation around the substrate binding pocket. Substantial differences between P450BM-3 and P450cam, the only other P450 structure available, are observed around the substrate binding pocket and the regions important for redox partner binding. A general mechanism for proton transfer in P450's is also proposed.
