additional information | modification of the chemo- and regioselectivity of AurH by site-directed mutagenesis, yielding mutants that catalyze the regioselective six-electron transfer of a nonactivated methyl group to a carboxylic acid via hydroxyl and aldehyde intermediates, overview | Streptomyces thioluteus |
Inhibitors | Comment | Organism | Structure |
---|---|---|---|
Ancymidol | a P450 inhibitor, that induces conformational changes at the active site. It is primarily bound through the interaction of the pyrimidine ring system to the heme iron and to the conserved residue T247. Other interactions to the inhibitor are mediated by loose and hydrophobic contacts, mainly to residues F89, A243, L175, L290, T295 | Streptomyces thioluteus |

additional information | AurH catalyzes an unprecedented tandem oxygenation process. First, AurH catalyzes an asymmetric hydroxylation of deoxyaureothin, yielding (7R)-7-hydroxydeoxyaureothin as an intermediate, thus setting the absolute configuration of the final product. Second, AurH mediates another C-O bond formation that leads to O-heterocyclization.
