متن کاملInhibitory effect of vitamin E on vitamin B2-aldehyde-forming enzyme in Schizophyllum commune.
The novel enzyme of Schizophyllum commune which converts the 5•L hydroxymethyl group of riboflavin to the aldehyde group has been found to be unable to use NAD(P)+, FMN, FAD and Cyt c as electron acceptor for the conversion, as reported previously (1 , 2). During further investigation on the reaction mechanism of the enzyme , we have found a significant inhibition of the enzyme by ƒ¿-tocopherol...
متن کاملVitamin B2 (riboflavin) and a mixture of vitamin B2 and C affects MMC efficiency in aerated media under irradiation.
Vitamin B2 (Riboflavin) acts as a strong radiation protecting agent in Escherichia coli bacteria (AB1157) in aerated media. This ability is reinforced by the addition of vitamin C. Under the influence of gamma-radiation, vitamin B2 completely suppresses the cytostatic activity of mitomycin C (MMC). In the presence of both vitamins, B2 and C, MMC is converted from an efficient cytostatic to a ra...
