GlnB and GlnK are ancient signalling proteins that play a crucial role in the regulation of nitrogen assimilation. Both protein types can be present in the same genome as either single or multiple copies. However, the gene product of glnK is always found in an operon together with an amt gene encoding an ammonium-transport (Amt) protein. Complex formation between GlnK and Amt blocks ammonium uptake and depends on the nitrogen level in the cell, which is regulated through the binding of specific ...[more]
