The soluble methane monooxygenase (sMMO; EC 1.14.13.25) from the, pseudothermophile Methylococcus capsulatus (Bath) is a three-component, enzyme system that catalyzes the selective oxidation of methane to, methanol. We have used NMR spectroscopy to produce a highly refined, structure of MMOB, the 16-kDa regulatory protein of this system. This, structure has a unique and intricate fold containing seven beta-strands, forming two beta-sheets oriented perpendicular to each other and bridged, by three alpha-helices. The rate and efficiency of the methane, hydroxylation by sMMO depend on dynamic binding interactions of the, hydroxylase with the reductase and regulatory protein components during, catalysis. We have monitored by NMR the binding of MMOB to the hydroxylase, in the presence and absence of the reductase. The results of these studies, provide structural insight into how the regulatory protein interacts with, the hydroxylase.

== Function ==
 +
[https://www.uniprot.org/uniprot/MMOB_METCA MMOB_METCA] The B protein acts as a regulator of electron flow through the soluble mmo complex, switching the enzyme from an oxidase to a hydroxylase in the presence of the substrate.

We have used NMR spectroscopy to produce a highly refined structure of MMOB, the 16-kDa regulatory protein of this system. This structure has a unique and intricate fold containing seven beta-strands forming two beta-sheets oriented perpendicular to each other and bridged by three alpha-helices. The rate and efficiency of the methane hydroxylation by sMMO depend on dynamic binding interactions of the hydroxylase with the reductase and regulatory protein components during catalysis. We have monitored by NMR the binding of MMOB to the hydroxylase in the presence and absence of the reductase. The results of these studies provide structural insight into how the regulatory protein interacts with the hydroxylase.
