Short-Term Regulation of the Nitrogenase Activity in Rhodopseudomonas sphaeroides

Autor: Klaas J. Hellingwerf, Cees Veeger, Huub Haaker, Colja Laane, Wil N. Konings, Berend Houwer

Publikováno v: European Journal of Biochemistry. 127:639-646

The nitrogenase activity in whole cells of Rhodopseudomonas sphaeroides could be inhibited by lowering the electrical potential across the cytoplasmic membrane. The membrane potential was partly dissipated either by lowering the light intensity or by

Role of Riboflavin in Beer Flavor Instability: Determination of Levels of Riboflavin and Its Origin in Beer by Fluorometric Apoprotein Titration

Autor: David J Evans, Riet Hilhorst, Diederik J M Schmedding, Martina G Duyvis, Colja Laane

Publikováno v: Journal of Agricultural and Food Chemistry. 50:1548-1552

A method for the quantitative determination of riboflavin levels in beer was developed. The method is based on the quenching of riboflavin fluorescence, which occurs when riboflavin binds to the aporiboflavin-binding protein from egg white. The metho
