Moco Riboswitch

The molybdenum cofactor (moco) riboswitch is an RNA element which responds to the presence of the metabolite molybdenum cofactor. This RNA element is located in the E.coli genome just upstream of the moaABCDE operon, which contain the important moco synthesis genes. The moco riboswitch has 2 regions: an aptamer domain and the expression platform. When moco is present in the cell it will bind to the aptamer region in the riboswitch which will cause an allosteric change. This allosteric change affects the expression platform by physically hiding the ribosome binding site thus preventing translation from occurring and hence adding a translational level of gene expression regulation. Therefore, the moco riboswitch, when activated by moco, inhibits gene expression.
