Amino acid sequence homology between CMO and other proteins with Rieske-type iron-sulfur centers

Sequence	Species	Size of region compared residues	Identity, %	Similarity, %
Naphthalene dioxygenase	Pseudomonas putida	195	29.2	43.0
Vanillate demethylase (hydroxylase component)	Pseudomonas sp.	58	31.0	43.0
Mitochondrial Rieske Fe-S protein	Zea mays	72	29.2	36.1

The data shown are for representative members of the bacterial aromatic-ring dioxygenase and alkyl-group hydroxylase families (8) and of the Rieske protein family. The regions of homology that were compared included the conserved [2Fe-2S] cluster binding motif. Local homologies were first identified using blastp with nonredundant sequences in the National Center for Biotechnology Information (NCBI) database and individual entries were compared by fasta.
