P4H is a key player in collagen accumulation, which has implications in fibrotic disorders. The stabilization of collagen triple-helical structure via prolyl hydroxylation is the rate-limiting step in collagen biosynthesis, and therefore P4H has been extensively investigated as a potential therapeutic target of fibrotic disease. Understanding how these enzymes recognize cofactors and substrates is important and will aid in the future design of inhibitors of P4H. In this article, X-ray crystal structures of a metallocofactor- and alpha-ketoglutarate (alphaKG)-bound form of P4H from Bacillus anthracis (BaP4H) are reported. Structures of BaP4H were solved at 1.63 and 2.35 A resolution and contained a cadmium ion and alphaKG bound in the active site. The alphaKG-Cd-BaP4H ternary complex reveals conformational changes of conserved residues upon the binding of metal ion and alphaKG, resulting in a closed active-site configuration required for dioxygen, substrate binding and catalysis.
