[https://www.uniprot.org/uniprot/ATSK_PSEPU ATSK_PSEPU] Catalyzes the oxigenolytic cleavage of 2-ethylhexyl sulfate (2-EHS) in the presence of alpha-ketoglutarate to yield 2-ethyl-hexanal and succinate, the decarboxylated form of alpha-ketoglutarate. It can accepte a wide range of alpha-keto acids including 2-oxo-valerate, 2-oxo-adipate, 2-oxo-octanoate, 3-methyl-2-oxo-butyrate, oxaloacetate-alpha-ketoadipate, and alpha-ketooctanoate. It can catalyze the cleavage of medium-chain alkyl sulfate esters such as butylsulfate, pentylsulfate, hexylsulfate, heptylsulfate, octylsulfate, nonylsulfate, decylsulfate and sodium dodecyl sulfate (SDS).<ref>PMID:10913158</ref>

== Publication Abstract from PubMed ==
 +
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 taurine/alpha-ketoglutarate dioxygenase TauD and is similar to the fold observed for other members of the enzyme superfamily. From comparison of these structures with the crystal structure of AtsK and its complexes, we propose a general mechanism for the catalytic cycle of the alpha-ketoglutarate-dependent dioxygenase superfamily.
