| Comments |
"The E. coli chemotaxis signaling pathway can amplify
stimuli at least 50-fold (i.e. a 1% change in receptor occupancy
elicits a 50% change in the rotational bias of the
flagellar motors [primary source], a minimal estimate because receptors
act in intermixed arrays [PMID 11742065])." |
