Hydroxynitrile Lyases: Biological Sources and Application as Biocatalysts

Autor: Herfried Griengl, Martin H. Fechter

Publikováno v: Food Technology and Biotechnology, Vol 42, Iss 4, Pp 287-294 (2004)

We review the state of the art regarding the application of hydroxynitrile lyases to obtain, enantioselectively, (R)- and (S)-cyanohydrins of aldehydes and ketones. Special emphasis is given to recent preparative applications and to research for exte

The synthesis of chiral cyanohydrins by oxynitrilases

Autor: Martin H. Fechter, Herfried Griengl, Helmut Schwab

Publikováno v: Trends in Biotechnology. 18:252-256

Enantiomerically pure cyanohydrins are important synthetic intermediates for pharmaceuticals and agrochemicals. They are produced by enzyme-catalysed synthesis using oxynitrilases. Sufficient quantities of enzyme are available via cheap natural sourc

Synthetic applications of glucose isomerase: isomerisation of C-5-modified (2R,3R,4R)-configured hexoses into the corresponding 2-ketoses

Autor: Arnold E. Stütz, Martin H. Fechter

Publikováno v: Carbohydrate Research. 319:55-62

Immobilised glucose isomerase (EC 5.3.1.5) accepted various (2 R ,3 R ,4 R )-configured hexoses such as 5-deoxy- d - ribo -hexose, 5-azido-5-deoxy- d -allose, as well as the corresponding epimer at C-5, 5-azido-5-deoxy- l -talose, as substrates. From
