FE-SUCCINATE COMPLEX OF ATSK
Overview
The alkylsulfatase AtsK from Pseudomonas putida S-313 is a member of the, non-heme iron(II)-alpha-ketoglutarate-dependent dioxygenase superfamily., In the initial step of their catalytic cycle, enzymes belonging to this, widespread and versatile family coordinate molecular oxygen to the iron, center in the active site. The subsequent decarboxylation of the, cosubstrate alpha-ketoglutarate yields carbon dioxide, succinate, and a, highly reactive ferryl (IV) species, which is required for substrate, oxidation via a complex mechanism involving the transfer of radical, species. Non-productive activation of oxygen may lead to harmful side, reactions; therefore, such enzymes need an effective built-in protection, mechanism. One of the ways of controlling undesired side reactions is the, ... [(full description)]
