Abstract
Recently, the enzyme family of oleate hydratases (OHs: EC 4.2.1.53) has gained increasing scientific and economic interest, as these FAD‐binding bacterial enzymes do not require cofactor recycling and possess high thermal and pH stability. Their products, hydroxy fatty acids, are used in specialty chemical applications including surfactant and lubricant formulations. The “oleate hydratase engineering database”, established by Schmid et al. (2017), divides all OHs into 11 families (HFam1 to 11). To date, only two crystal structures of homodimeric OHs from the families HFam2 and HFam11 have been reported. In this study, we biophysically characterized an OH belonging to the HFam3 family, originating from the marine bacterium Rhodococcus erythropolis, for the first time. The crystal structure revealed that this new OH (OhyRe) surprisingly is a monomer in its active form. This particular feature provides new avenues for enzyme engineering and recycling through immobilization.
