From: Antibacterial activity of the nitrovinylfuran G1 (Furvina) and its conversion products
Colorimetric measurement of G1 reactivity with cysteine.
Absorbance spectra of G1 and its reaction products obtained at different concentrations of cysteine hydrochloride (A). G1 at the concentration of 16 μg/ml (0.054 mM) was added 5 seconds after the start of the A390 measurement and reacted with cysteine hydrochloride in M9 minimal medium. Measurements were carried out at pH 7.4 using different concentrations of cysteine (B) and at different pH values in the presence of 100 μg/ml cysteine hydrochloride (C).
