Evidence Evidence demonstrating that the participating proteins are unstructured prior to the interaction and their folding is coupled to binding.

Representative domain in related structures: Glyoxalase/Bleomycin resistance protein/Dioxygenase superfamily

Evidence level: Indirect evidence

Evidence coverage: The full structure participates in mutual synergistic folding.

Complex Evidence:

The VOC superfamily of metalloenzymes is characterized by a three-dimensional domain-swapped arrangement of tandem βαβββ-motifs (PMID:24447055). The original gene duplication event led to the βαβββ tandem structure, which appears to require dimerization for stability. Two different forms of domain-swapped dimers may coexist in solution (PMID:12121648) in which both subunits of the homodimer participate in coordination of each metal ion and formation of the U-shaped active sites in the enzyme (PMID:24004181). The complex is predominantly dimeric in solution (gel filtration) (PMID:12121648).

Surface and contacts features:

Related Structure(s) Structures from the PDB that contain the same number of proteins, and the proteins from the two structures show a sufficient degree of pairwise similarity, i.e. they belong to the same UniRef90 cluster (the full proteins exhibit at least 90% sequence identity) and convey roughly the same region to their respective interactions (the two regions from the two proteins share a minimum of 70% overlap).
