Chemically inactivated nitrate reductase of Neurospora crassa strain al‐2, bd can be photoreactivated by blue light. The quantum requirement for this reaction in the presence of exogenous FMN was determined with different light intensities. The results are discussed with the alternate assumptions that free FMN or photoactivated FAD bound to the nitrate reductase molecule is the reactivating species.
