The cyanobacterium Synechocystis sp. PCC 6803 possesses an arsenic resistance operon that encodes, among others, an ArsH protein. ArsH is a flavin mononucleotide (FMN)-containing protein of unknown function and a member of the family of NADPH-dependent FMN reductases. The nature of its final electron acceptor and the role of ArsH in the resistance to arsenic remained to be clarified. Here we have expressed and purified Synechocystis ArsH and conducted an intensive biochemical study. We present… CONTINUE READING
