additional information no changes are found in the kinetics of reduction of the FMN cofactor of flavodoxin modified by glycine ethyl ester as compared with the native protein (reaction of EC 1.19.1.1). The observed rate constants for reoxidation of ferredoxin by FNR are about 100fold decreased when phenylglyoxal-modified FNR is used Nostoc sp. ?
