Spectrophotometric studies on lysine monooxygenase, a flavoprotein.

Regulatory properties of the flavoprotein L-lysine monooxygenase.

The Structure of the Antibiotic Deactivating, N-hydroxylating Rifampicin Monooxygenase.

Rifampicin monooxygenase (RIFMO) catalyzes the N-hydroxylation of the natural product antibiotic rifampicin (RIF) to 2'-N-hydroxy-4-oxo-rifampicin, a metabolite with much lower antimicrobial activity. RIFMO shares moderate sequence similarity with well characterized flavoprotein monooxygenases, but the protein has not been isolated and characterized at the molecular level. Herein, we report cry...

Form Follows Function: Structural and Catalytic Variation in the Class A Flavoprotein Monooxygenases

Flavoprotein monooxygenases (FPMOs) exhibit an array of mechanistic solutions to a common chemical objective; the monooxygenation of a target substrate. Each FPMO efficiently couples reduction of a flavin cofactor by NAD(P)H to oxygenation of the target substrate via a (hydro)peroxyflavin intermediate. This purpose of this review is to describe in detail the Class A flavoprotein hydroxylases (F...

StyA1 and StyA2B from Rhodococcus opacus 1CP: a multifunctional styrene monooxygenase system.

Two-component flavoprotein monooxygenases are emerging biocatalysts that generally consist of a monooxygenase and a reductase component. Here we show that Rhodococcus opacus 1CP encodes a multifunctional enantioselective flavoprotein monooxygenase system composed of a single styrene monooxygenase (SMO) (StyA1) and another styrene monooxygenase fused to an NADH-flavin oxidoreductase (StyA2B). St...

Biochemical and Mechanistic Studies of Nitronate Monooxygenase and Roles of Histidine Residues in Select Flavoprotein Oxidases

Nitronate monooxygenase (NMO) catalyzes the flavin-dependent oxidation of propionate 3-nitronate (P3N) via the formation of an anionic flavosemiquinone. The oxidation of substrate includes the formation of a peroxy-nitro acid intermediate. P3N is activated to its radical form via a single electron transfer onto the FMN cofactor forming the anionic flavosemiquinone. Reoxidation of FMN cofactor f...
