Cysteamine oxygenase: possible involvement of superoxide ion in the catalytic mechanism.
According to data, nitroblue tetrazolium is reduced by cysteamine or mercaptoethanol and phenazine methosulphate and this reaction is completely inhibited by superoxide dismutase.
Spectroscopic Investigation of Cysteamine Dioxygenase.
The authors' magnetic circular dichroism and electron paramagnetic resonance data provide compelling evidence that ADO features a 3-histidine facial triad, like CDO and MDO, demonstrating the significant role that secondary sphere residues play in dictating substrate specificity.
Discovery and Characterization of a Second Mammalian Thiol Dioxygenase, Cysteamine Dioxygenase*
Western blots of murine tissues with an antibody developed against ADO showed that the protein is ubiquitously expressed with the highest levels in brain, heart, and skeletal muscle, suggesting that ADO is responsible for endogenous cysteamine dioxygenase activity.
Electron paramagnetic resonance study on metmyoglobin and nonheme iron formations in frozen tuna meats
Frozen storage is an important and convenient preservation method, effectively preserving fish and fish products for long periods of time. Tuna is usually frozen on board the fishing vessel and

Enzymes which catalyze the introduction of one or both atoms of a molecule of oxygen into an organic substrate are termed oxygenases, and mono- and dioxygenases in based on whether the enzyme causes transfer of just one atom to the substrate are classified.
Oxidation of some biologically active and related sulfur-containing compounds
Enzymic oxidations of thiols and disulfides are compared with their chemical oxidations with N 2 O 4 and H 2 O 2 by the use of unsymmetrical disulfide, thiolSulfinates and O 18 -tracer technique.
Synthetic Fe/Cu Complexes: Toward Understanding Heme-Copper Oxidase Structure and Function.
This review encompasses important aspects of heme-O 2 and copper-O2 (bio)chemistries as they relate to the design and interpretation of small molecule model systems and provides perspectives from fundamental coordination chemistry, which can be applied to the understanding of HCO activity.
