  α-ketoglutarate-dependent dioxygenase that catalyzes the oxidation and subsequent cleavage of alkyl sulfate esters. Rv3406 was identified based on its homology to the alkyl sulfatase AtsK from Pseudomonas putida. Using an in vitro biochemical assay, we confirmed that Rv3406 is a sulfatase with a preference for alkyl sulfate substrates similar to those processed by AtsK. We determined the crystal structure

• Characterization of a Sulfur-regulated Oxygenative Alkylsulfatase from Pseudomonas putida S-313

  The atsK gene of Pseudomonas putida S-313 was required for growth with alkyl sulfate esters as sulfur source. The AtsK protein was overexpressed in Escherichia coli and purified to homogeneity. Sequence analysis revealed that AtsK was closely related to E. coli taurine dioxygenase (38% amino acid identity). The AtsK protein catalyzed the alpha-ketoglutarate-dependent cleavage of a range of alkyl sulfate esters, with chain lengths ranging from C-4 to C-12, required oxygen and Fe2+ for activity and released succinate, sulfate, and the corresponding aldehyde as products. Enzyme activity was optimal at pH 7 and was strongly stimulated by ascorbate. Unlike most other characterized alpha-ketoglutarate-dependent dioxygenases, AtsK accepted a range of alpha-keto acids as co-substrates, including alpha-ketoglutarate (K-m 140 mu M), alpha-ketoadipate, alpha-ketovalerate, and alpha-ketooctanoate. The measured K-m values for hexyl sulfate and SDS were 40 and 34 mu M, respectively. The apparent M-r of the purified enzyme of 121,000 was consistent with a homotetrameric structure, which is unusual for this enzyme superfamily, members of which are usually monomeric or dimeric, The properties and amino acid sequence of the AtsK enzyme thus define it as an unusual oxygenolytic alkylsulfatase and a novel member of the alpha-ketoglutarate-dependent dioxygenase family.
