A, C, E	PF00848	Ring hydroxylating alpha subunit (catalytic domain) (Ring_hydroxyl_A)	Ring hydroxylating alpha subunit (catalytic domain)	This family is the catalytic domain of aromatic-ring- hydroxylating dioxygenase systems. The active site contains a non-heme ferrous ion coordinated by three ligands.	Domain
A, C, E	PF00355	Rieske [2Fe-2S] domain (Rieske)	Rieske [2Fe-2S] domain	The rieske domain has a [2Fe-2S] centre. Two conserved cysteines coordinate one Fe ion, while the other Fe ion is coordinated by two conserved histidines. In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in ...	The rieske domain has a [2Fe-2S] centre. Two conserved cysteines coordinate one Fe ion, while the other Fe ion is coordinated by two conserved histidines. In hyperthermophilic archaea there is a SKTPCX(2-3)C motif at the C-terminus. The cysteines in this motif form a disulphide bridge, which stabilises the protein [4].	Domain
B, D, F	PF00866	Ring hydroxylating beta subunit (Ring_hydroxyl_B)	Ring hydroxylating beta subunit	This subunit has a similar structure to NTF-2 and scytalone dehydratase.	Domain
