A Mushroom P450-Monooxygenase Enables Regio- and Stereoselective Biocatalytic Synthesis of Epoxycyclohexenones. Angew Chem Int Ed Engl 2023; 62:e202313817.

Abstract
An epoxycyclohexenone (ECH) moiety occurs in natural products of both bacteria and ascomycete and basidiomycete fungi. While the enzymes for ECH formation in bacteria and ascomycetes have been identified and characterized, it remained obscure how this structure is biosynthesized in basidiomycetes. In this study, we i) identified a genetic locus responsible for panepoxydone biosynthesis in the basidiomycete mushroom Panus rudis and ii) biochemically characterized PanH, the cytochrome P450 enzyme catalyzing epoxide formation in this pathway. Using a PanH-producing yeast as a biocatalyst, we synthesized a small library of bioactive ECH compounds as a proof of concept. Furthermore, homology modeling, molecular dynamics simulation, and site directed mutation revealed the substrate specificity of PanH. Remarkably, PanH is unrelated to ECH-forming enzymes in bacteria and ascomycetes, suggesting that mushrooms evolved this biosynthetic capacity convergently and independently of other organisms.

Abstract
Strategies for the synthesis of the title compounds have been developed using a diastereoselective aziridination reaction of 4-O-substituted cyclohexenones. Aziridination using a chiral amine permitted resolution of a 4-hydroxycyclohexane derivative, and this resulted in the synthesis of both enantiomers of the title compound. Alternatively, the chiral 4-hydroxycyclohexenone starting material was derived from quinic acid. In both cases stereoselective epoxidation and opening of the aziridine ring with hydrazoic acid afforded the 2-azidocyclohexenone, which was transformed to the 2-acetamido group present in the natural product.

Abstract
The amino-epoxyquinols 6a and 6b were synthesized as soluble derivatives of an NF-κB inhibitor DHMEQ (1). In spite of the opposite configuration from 1, 6b rather than 6a affected the deactivation of NF-κB, based on NO secretion and MALDI-TOF MS analysis. It was indicated that 6b inhibited the activation by different manner from that of 1.

Abstract
Three cyclohexenone derivatives, (4S,5S,6S)-5,6-epoxy-4-hydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (1), (4R,5R)-4,5-dihydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (2), and (4R,5S,6R)-4,5,6-trihydroxy-3-methoxy-5-methyl-cyclohex-2-en-1-one (3), were isolated from unpolished rice fermented with an xylariaceous endophytic fungus (strain YUA-026). The structures of three compounds were established on the basis of spectroscopic analyses and chemical conversion. The minimum inhibitory concentrations of 1 and 3 were 100 microg/ml and 400 microg/ml against Staphylococcus aureus, 100 microg/ml and 200 microg/ml against Pseudomonas aeruginosa, and 200 microg/ml and >400 microg/ml against Candida albicans, respectively. In addition, 1 and 3 exhibited phytotoxic activity against lettuce.

Abstract
(3-si,4-re)-2,5-Dihydroxyacetanilide epoxidase (DHAE I), a key enzyme in the biosynthesis of the epoxysemiquinone antibiotic LL-C10037 alpha by Streptomyces LL-C10037 [Gould, S.J., & Shen, B. (1991) J. Am. Chem. Soc. 113, 684-686], and (3-re,4-si)-2,5-dihydroxyacetanilide epoxidase (DHAE II) isolated from Streptomyces MPP 3051--which yields the (3R,4S)-epoxyquinone mirror image product of DHAE I--are described. DHAE I was purified 640-fold. Gel permeation chromatography indicated an Mr of 117,000 +/- 10,000; SDS-PAGE gave a major band of 22,300 daltons, indicating that DHAE I is either a pentamer or hexamer in solution. The enzyme had a pH optimum of 6.5, a Km of 8.4 +/- 0.5 microM, and a Vmax of 3.7 +/- 0.2 mumol min-1 mg-1. DHAE II was purified 1489-fold. The enzyme was shown to be a dimer of Mr 33,000 +/- 2000, with 16,000-dalton subunits, with a pH optimum of 5.5 and a Km of 7.2 +/- 0.4 microM. Both enzymes required only O2 and substrate; flavin and nicotinamide coenzymes had little or no effect. Neither catalase nor EDTA affected the activity of either enzyme, but complete inhibition of both was obtained with 1,10-phenanthroline. The activity of the purified DHAE I could be enhanced, but only by Mn2+ (relative V = 246 at 0.04 mM), Ni2+ (relative V = 266 at 0.2 mM), or Co2+ (relative = 498 at 0.2 mM). Reconstitution from a DHAE I apoenzyme, generated by treatment with 1,10-phenanthroline followed by Sephadex G-25 chromatography, occurred only by addition of one of these three metals.(ABSTRACT TRUNCATED AT 250 WORDS)
