Active with a wide range of aromatic and aliphatic primary alcohols and aldehydes: acts on alcohol groups and requires the spontaneous hydration of aldehyde groups for their oxidation (PubMed:24271187, PubMed:24802551). To a lesser extent, is also able to catalyze the oxidation of thiols that are structurally similar to its alcohol substrates, yielding the corresponding thiocarbonyls (PubMed:25284255).<ref>PMID:24271187</ref> <ref>PMID:24802551</ref> <ref>PMID:25284255</ref> | ||

| + | Various flavoprotein oxidases were recently shown to oxidize prim-thiols. Here we extend this reactivity towards sec-thiols via structure-guided engineering of 5-(hydroxymethyl)furfural oxidase (HMFO). The variants obtained were employed for the oxidative kinetic resolution of rac-sec-thiols yielding the correspon notding thioketones and nonreacted (R)-thiols with excellent enantioselectivities (E >/= 200). The engineering strategy applied went beyond the classic approach of replacing bulky amino acid residues with smaller ones, as the active site was additionally enlarged by a newly introduced Thr residue that establishes a hydrogen bonding interaction with the substrates, as predicted by modelling and verified in the crystal structure of the variant. These strategies unlocked HMFO variants for the enantioselective oxidation of a range of sec-thiols. | ||
