The AlkB Family of Fe(II)/α-Ketoglutarate-dependent Dioxygenases: Repairing Nucleic Acid Alkylation Damage and Beyond*

Journal of Biological Chemistry, 2015
The AlkB family of Fe(II)- and α-ketoglutarate-dependent dioxygenases is a class of ubiquitous direct reversal DNA repair enzymes that remove alkyl adducts from nucleobases by oxidative dealkylation.

Substrate Specificity in Thiol Dioxygenases.

Biochemistry, 2019
Thiol dioxygenases make up a class of ferrous iron-dependent enzymes that oxidize thiols to their corresponding sulfinates. X-ray diffraction structures of cysteine-bound cysteine dioxygenase show how cysteine is coordinated via its thiolate and amine to

Four Aromatic Intradiol Ring Cleavage Dioxygenases from Aspergillus niger

Applied and Environmental Microbiology, 2019
Aromatic ring opening using molecular oxygen is one of the critical steps in the degradation of aromatic compounds by microorganisms. While enzymes catalyzing this step have been well-studied in bacteria, their counterparts from fungi are poorly ...
