A	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

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
