Two enzymes, S-adenosylmethionine decarboxylase and spermidine synthase, are essential for the biosynthesis of spermidine in Escherichia coli. We have previously shown that the genes encoding these enzymes (speD and speE) form an operon and that the area immediately upstream from the speE gene is necessary for the expression of both the speE and speD genes. We have now studied the upstream promoter and the downstream terminator regions of this operon more completely. We have shown that the major ...[more]
