Genetic suppression meets structure prediction: probing a spore germination receptor complex.

Despite the thousands of spore germinant receptor operons identified in genomes of Bacilli and Clostridia, understanding how the three essential receptor components act as a signal transduction machine in germination remains limited. The paper by Amon et al in this issue uses the classical genetic approach of suppression to define a region of likely interaction between the GerAA and GerAB proteins: it provides a first glimpse into potential events within the receptor complex.
