This entry represents the C-terminal domain of a Rieske oxygenase enzyme. This entry includes the 5,5'-dehydrodivanillate O-demethylase three-component monooxygenase which is composed of an oxygenase (LigXa) in this entry, a ferredoxin (LigXc) and a ...
This entry represents the C-terminal domain of a Rieske oxygenase enzyme. This entry includes the 5,5'-dehydrodivanillate O-demethylase three-component monooxygenase which is composed of an oxygenase (LigXa) in this entry, a ferredoxin (LigXc) and a ferredoxin reductase (LigXd) [1].
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].
