Abstract

Methane monooxygenases catalyse the oxidation of methane to methanol in the presence of oxygen and NADH in methanotrophs. It has a broad specificity, hydroxylating many alkanes, and converting alkenes into the corresponding epoxides. In additional reactions, CO is oxidized to CO2, ammonia is oxidized to hydroxylamine, and some aromatic compounds and cyclic alkanes can also be hydroxylated, although more slowly. In Methylococcus capsulatus there are two forms of the enzyme, a soluble and a membrane-bound type. The soluble form consists of 3 components, A, B and C. Protein A is made up of 3 chains, alpha, beta and gamma.

This entry represents the gamma chain of methane monooxygenases. Structurally, the gamma chain contains two domains, each consisting of a three helices arranged in an open bundle topology [].

Browse genome assignments for this superfamily. The SUPERFAMILY hidden Markov model library has been used to carry out SCOP domain assignments to all genomes at the superfamily level.


Alignments of sequences to 2 models in this superfamily are available by clicking on the 'Alignments' icon above. PDB sequences less than 40% identical are shown by default, but any other sequence(s) may be aligned. Select PDB sequences, genome sequences, or paste in or upload your own sequences.


Browse and view proteins in genomes which have different domain combinations including a Methane monooxygenase hydrolase, gamma subunit domain.


Examine the distribution of domain superfamilies, or families, across the major taxonomic kingdoms or genomes within a kingdom. This gives an immediate impression of how superfamilies, or families, are restricted to certain kingdoms of life.


Explore domain occurrence network where nodes represent genomes and edges are domain architectures (shared between genomes) containing the superfamily of interest.

There are 2 hidden Markov models representing the Methane monooxygenase hydrolase, gamma subunit superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
