3,3’-Thiodipropionic acid (TDP) is used as an additive in food and cosmetic industry and as precursor substrate for biotechnical polythioester production. Its catabolism was investigated inVariovorax paradoxusTBEA6 previous to this study. It was reported that the insertion of the transposon Tn5::mobinto a gene showing high homology to flavin-dependent oxidoreductases (fox) resulted in impaired growth with TDP. Therefore, it was assumed that the initial cleavage of TDP is catalyzed by an FAD-dependent oxidoreductase (Fox, VPARA_05580). Accordingly,foxwas heterologously expressed as a thioredoxin fusion protein. Analytical size exclusion chromatography revealed a homodimeric structure and the presence of the cofactor FAD.In vitroexperiments showed that FoxTBEA6is a D-2-hydroxy acid specific dehydrogenase and that its activity is enhanced in presence of either Ni2+, Co2+or Zn2+. Cleavage of TDP by FoxTBEA6was not observed. The findings are contrary to restricted growth with TDP of the transposon mutants and the previously published deletion mutantV. paradoxusTBEA6 Δfox. In this study, this contradiction was investigated by generation of additional deletion mutants, in which partial or complete deletion offoxdid not affect utilization of TDP, and the mapping of single nucleotide polymorphisms (SNPs) inV. paradoxusTBEA6 Δfox.
