Geobacter sulfurreducens AM-1 can use methacrylate as a terminal electron acceptor for anaerobic respiration. In this paper, we report on the purification and properties of the periplasmic methacrylate reductase, and show that the enzyme is dependent on the presence of a periplasmic cytochrome c (apparent K(m) = 0.12 microM). The methacrylate reductase was found to be composed of only one polypeptide with an apparent molecular mass of 50 kDa and to contain, bound tightly but not covalently, 1… CONTINUE READING
