Abstract
The article by Lewis et al. (https://doi.org/10.1085/jgp.202413709) in this issue of JGP describes the use of single-molecule fluorescence polarization microscopy to obtain estimates of all the rate constants for transitions in the catalytic cycle of AdiC, a bacterial transporter for arginine and agmatine that has been believed to be a 1:1 exchanger.
期刊介绍:
General physiology is the study of biological mechanisms through analytical investigations, which decipher the molecular and cellular mechanisms underlying biological function at all levels of organization.
The mission of Journal of General Physiology (JGP) is to publish mechanistic and quantitative molecular and cellular physiology of the highest quality, to provide a best-in-class author experience, and to nurture future generations of independent researchers. The major emphasis is on physiological problems at the cellular and molecular level.
