Expression, purification, crystallization and preliminary X-ray studies of a prolyl-4-hydroxylase protein from Bacillus anthracis.
Collagen prolyl-4-hydroxylase (C-P4H) catalyzes the hydroxylation of specific proline residues in procollagen, which is an essential step in collagen biosynthesis. A new form of P4H from Bacillus anthracis (anthrax-P4H) that shares many characteristics with the type I C-P4H from human has recently been characterized. The structure of anthrax-P4H could provide important insight into the chemistry of C-P4Hs and into the function of this unique homodimeric P4H. X-ray diffraction data of selenomethionine-labeled anthrax-P4H recombinantly expressed in Escherichia coli have been collected to 1.4 A resolution.
