Popis: The RquA protein is required for rhodoquinone biosynthesis; however, its exact function is not yet known. Here, the authors demonstrate that RquA is homologous to SAM-dependent methyltransferases but functions as an aminotransferase using Mn2+ as cofactor to convert ubiquinone to rhodoquinone.
