A comparative molecular field analysis of the biotransformation of sulfides by Rhodococcus erythropolis
Autor: Herbert L. Holland, Heather L. Gordon, Jarrod B. French, Giles Holland
Publikováno v: Journal of Molecular Catalysis B: Enzymatic. 31:87-96
A comparative molecular field analysis (CoMFA) was used to model the efficacy with which the Rhodococcus erythropolis mono-oxygenase, DszC, catalyzes the enantioselective sulfoxidation of a broad range of substrates. Experimentally determined values

Biocatalytic oxidation of S-alkylcysteine derivatives by chloroperoxidase and Beauveria species
Autor: Dean V. Johnson, Benjamin Mayne, Herbert L. Holland, Frances M. Brown, Carl D Turner, Aaron J van Vliet, Ali Kerridge
Publikováno v: Journal of Molecular Catalysis B: Enzymatic. 17:249-256
Treatment of N -methoxycarbonyl C -carboxylate ester derivatives of S -methyl- l -cysteine by chloroperoxidase (CPO)/hydrogen peroxide resulted in oxidation at sulfur to produce the ( R S ) sulfoxide in moderate to high diastereomeric excess (DE). Th

Autor: Frances M. Brown, Benjamin Mayne, W. Rick Szerminski, Aaron J van Vliet, Damian Lozada, Herbert L. Holland
Publikováno v: Canadian Journal of Chemistry. 80:633-639
Treatment of N-methoxycarbonyl C-carboxylate ester derivatives of L- and D-methionine and L-ethionine by chloroperoxidase–hydrogen peroxide resulted in oxidation at sulfur to produce the (RS) sulfoxide in moderate to high diastereomeric excess. The

Enzymatic hydroxylation reactions
Autor: Hedda K. Weber, Herbert L. Holland
Publikováno v: Current Opinion in Biotechnology. 11:547-553
During the past 18 months, considerable progress has been made in the understanding of the key enzyme–substrate interactions that control the regioselectivity and stereoselectivity of the hydroxylation reaction performed by cytochrome-P450-dependen

Probing the scope of the sulfoxidation activity of vanadium bromoperoxidase from Ascophyllum nodosum
Autor: Herbert L. Holland, Hester L. van Lingen, Hans E. Schoemaker, Ron Wever, Hilda B. ten Brink
Publikováno v: Tetrahedron-Asymmetry, 10, 4563-4572. Elsevier
It has been shown previously that the vanadium bromoperoxidase from Ascophyllum nodosum mediates the production of ( R )-methyl phenyl sulfoxide with 91% enantiomeric excess from the corresponding sulfide in the presence of hydrogen peroxide. Investi
