Receptor interactions in a signalling system: competition between ribose receptor and galactose receptor in the chemotaxis response.


Galactose and ribose receptors are shown to compete for a common site by comparing the specificities of the purified receptors with the specificity of the whole organism response. Ribose does not bind to the purified galactose receptor but inhibits the in vivo galactose response. A mutant lacking the ribose receptor shows no inhibition of the galactose… (More)
