A ketone monooxygenase was purified from cells of Pseudomonas cepacia grown on 2-tridecanone as sole carbon source. Enzyme stability is maintained by the addition of ethanol, EDTA, and dithiothreitol. Stoichiometric studies show that for 1 mol of undecyl acetate formed, 1 mol of O2 is consumed and 1 mol of NADPH is oxidized. The monooxygenase, purified to homogeneity, has a molecular weight of approximately 123,000 and consists of two equal subunits with molecular weights of 55,000. The enzyme… Expand
Characterization of an FMN-containing cyclohexanone monooxygenase from a cyclohexane-grown Xanthobacter sp.
Kinetic investigations under steady-state conditions demonstrate that the flavoprotein prosthetic group, FMN, is involved in the monooxygenase catalytic mechanism. Expand
Bacterial steroid monooxygenase catalyzing the Baeyer-Villiger oxidation of C21-ketosteroids from Rhodococcus rhodochrous: the isolation and characterization.
It is clarified that bacterial steroid monooxygenase is distinctly different from the fungal enzyme in the molecular and enzymic properties. Expand
Conversion of 4-Hydroxyacetophenone into 4-Phenyl Acetate by a Flavin Adenine Dinucleotide-Containing Baeyer-Villiger-Type Monooxygenase
An arylketone monooxygenase was purified from Pseudomonas putida JD1 by ion exchange and affinity chromatography and converted its substrate, 4-hydroxyacetophenone, into 4-Hydroxyphenyl acetate with the consumption of one molecule of oxygen and oxidation of one molecules of NADPH per molecule of substrate.

Substrate Specificity and Enantioselectivity of 4-Hydroxyacetophenone Monooxygenase
The biocatalytic properties of HAPMO described here show the potential of this enzyme for biotechnological applications and is efficient and highly selective in the asymmetric formation of the corresponding (S)-sulfoxides. Expand
Novel Acetone Metabolism in a Propane-Utilizing Bacterium, Gordonia sp. Strain TY-5
Evidence is provided for BVMO-dependent acetone metabolism, which indicates that the acmAB gene products play an important role in the metabolism of acetone derived from propane oxidation and clarify the propane metabolism pathway of strain TY-5. Expand
The Prodrug Activator EtaA from Mycobacterium tuberculosis Is a Baeyer-Villiger Monooxygenase*
EtaA is a newly identified FAD-containing monooxygenase that is responsible for activation of several thioamide prodrugs in Mycobacterium tuberculosis. It was found that purified EtaA displays aExpand
Enzymic Baeyer–Villiger Oxidations by Flavin‐Dependent Monooxygenases
There has recently been a revival of interest in microbial biochemistry. Part of this resurgence is due to the increased presence of man-made organic compounds in the biosphere and the resultantExpand
Diversity of Alkane Hydroxylase Systems in the Environment
The first step in the aerobic degradation of alkanes by bacteria, yeasts, and fungi is catalyzed by oxygenases. These enzymes, which introduce oxygen atoms derived from molecular oxygen into theExpand
Cloning, expression and characterization of a Baeyer-Villiger monooxygenase from Pseudomonas putida KT2440
The gene encoding a Baeyer-Villiger monooxygenase and identified in Pseudomonas putida KT2440 was cloned and functionally expressed in Escherichia coli and revealed a high specificity towards short-chain aliphatic ketones. Expand
Enzymatic Conversion of Averufin to Hydroxyversicolorone and Elucidation of a Novel Metabolic Grid Involved in Aflatoxin Biosynthesis
Two kinds of reactions are involved in the pathway from AVR to VHA in aflatoxin biosynthesis, and a new metabolic grid, catalyzed by a new cytosol monooxygenase enzyme and the previously reported VHA reductase enzyme, composed of HVN, VONE, VOAc, and VHA is discovered. Expand
