CRYSTAL STRUCTURE OF THE ALKYLSULFATASE ATSK, A NON-HEME FE(II) ALPHAKETOGLUTARATE DEPENDENT DIOXYGENASE IN COMPLEX WITH IRON AND ALPHAKETOGLUTARATE
OverviewOverview
The alkylsulfatase AtsK from Pseudomonas putida S-313 belongs to the, widespread and versatile non-heme iron(II) alpha-ketoglutarate-dependent, dioxygenase superfamily and catalyzes the oxygenolytic cleavage of a, variety of different alkyl sulfate esters to the corresponding aldehyde, and sulfate. The enzyme is only expressed under sulfur starvation, conditions, providing a selective advantage for bacterial growth in soils, and rhizosphere. Here we describe the crystal structure of AtsK in the apo, form and in three complexes: with the cosubstrate alpha-ketoglutarate, with alpha-ketoglutarate and iron, and finally with alpha-ketoglutarate, iron, and an alkyl sulfate ester used as substrate in catalytic studies., The overall fold of the enzyme is closely related to that of the, ...
