Interactioni

Subunit structurei

The naphthalene dioxygenase (NDO) multicomponent enzyme system is composed of an electron transfer component and an oxygenase component. The electron transfer component is comprised of a ferredoxin reductase (NagAa) and a ferredoxin (NagAb), and the oxygenase component is formed by a large subunit (NagAc) and a small subunit (NagAd).2 Publications

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
