Abstract Eukaryotic and prokaryotic molybdoenzymes require a molybdopterin cofactor (MoCF) for their activity. The biosynthesis of this cofactor involves a complex multistep enzymatic pathway. One of the eukaryotic proteins involved in this pathway is the Drosophila protein cinnamon [PubMed8088525] which is highly similar to gephyrin, a rat microtubule-associated protein which was thought to anchor the glycine receptor to subsynaptic microtubules.

Cinnamon and gephyrin are evolutionary related, in their N-terminal half, to the Escherichia coli MoCF biosynthesis proteins mog/chlG and moaB/chlA2 and, in their C-terminal half, to E. coli moeA/chlE.

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 12 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 Molybdenum cofactor biosynthesis proteins 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 12 hidden Markov models representing the Molybdenum cofactor biosynthesis proteins superfamily. Information on how the models are built, and plots showing hydrophobicity, match emmission probabilities and insertion/deletion probabilities can be inspected.
