本酶催化的反应为L-Glutamate + FMN + O2 + H2O + 3 Acceptor = 2-Oxoglutarate + 8-Amino-8-Demethylriboflavin 5'-Phosphate + CO2 + 3 Reduced Acceptor (Overall Reaction);;(1a) FMN + O2 = 8-Demethyl-8-Formylriboflavin 5'-Phosphate + H2O;;(1b) 8-Demethyl-8-Formylriboflavin 5'-Phosphate + H2O + Acceptor = 8-Carboxy-8-Demethylriboflavin 5'-Phosphate + Reduced Acceptor;;(1c) L-Glutamate + 8-Carboxy-8-Demethylriboflavin 5'-Phosphate + H2O + 2 Acceptor = 2-Oxoglutarate + 8-Amino-8-Demethylriboflavin 5'-Phosphate + CO2 + 2 Reduced Acceptor，系统名称为L-Glutamate:FMN Aminotransferase (Oxidizing, Decarboxylating)，该酶源自达瓦链霉菌（Streptomyces davawensis），具有氧化还原酶、脱羧酶和氨基转移酶三种活性。这些活性的协同作用导致 FMN 一个芳香环上的甲基取代基被氨基置换，这是玫瑰黄素（roseoflavin）生物合成途径中的一步。该反应需要硫胺素才能完成。
