Protein Family Models

This domain is found a variety of proteins involved in biosynthesis of molybdopterin cofactor. The domain is presumed to bind molybdopterin. The structure of this domain is known, and it forms an alpha/beta structure. In the known structure of Gephyrin this domain mediates trimerisation [1]. [1]. 11325967.

molybdenum cofactor biosynthesis protein B (MoaB) similar to Pyrococcus furiosus MoaB; may be a metal-binding pterin (MPT)-adenylyltransferase which converts MPT to adenylylated MPT (MPT-AMP)

The Drosophila protein cinnamon, the Arabidopsis protein cnx1, and rat protein gephyrin each have one domain like MoeA and one like MoaB and Mog. These domains are, however, distantly related to each other, as captured by this HMM. Gephyrin is unusual in that it seems to be a tubulin-binding neuroprotein involved in the clustering of both blycine receptors and GABA receptors, rather than a protein of molybdenum cofactor biosynthesis.
