METHANE MONOOXYGENASE HYDROXYLASE FROM METHYLOCOCCUS CAPSULATUS (BATH)
Overview
The crystal structure of the nonheme iron-containing hydroxylase component, of methane monooxygenase hydroxylase (MMOH) from Methylococcus capsulatus, (Bath) has been solved in two crystal forms, one of which was refined to, 1.7 A resolution. The enzyme is composed of two copies each of three, subunits (alpha 2 beta 2 gamma 2), and all three subunits are almost, completely alpha-helical, with the exception of two beta hairpin, structures in the alpha subunit. The active site of each alpha subunit, contains one dinuclear iron center, housed in a four-helix bundle. The two, iron atoms are octahedrally coordinated by 2 histidine and 4 glutamic acid, residues as well as by a bridging hydroxide ion, a terminal water, molecule, and at 4 degrees C, a bridging acetate ion, which is replaced at, ...
