Abstract

Methenyltetrahydromethanopterin cyclohydrolase catalyses the interconversion of methenyltetrahydromethanopterin and N(5)formyltetrahydromethanopterin, and is found in both archaea and bacteria. In methanogenic archaea, such as Methanobacterium thermoautotrophicum (strain Marburg / DSM 2133), this enzyme is involved in the production of methane from carbon dioxide [PubMed8617278]. In the sulphate-reducer Archaeoglobus fulgidus, this enzyme is involved in the tetrahydromethanopterin-dependent oxidation of lactate [PubMed8481088]. In Gram-negative methylotrophic bacteria this enzyme is involved in the tetrahydromethanopterin-dependent oxidation of formaldehyde to formate [PubMed10482517].

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 1 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 Methenyltetrahydromethanopterin cyclohydrolase 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 1 hidden Markov models representing the Methenyltetrahydromethanopterin cyclohydrolase superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
