L(+)-Lactate binding to preparations of rat hepatocyte plasma membranes.


Incubation of rat hepatocyte plasma membranes with L-[14C]lactate resulted in the labeling of protein(s) of apparent molecular weight 40,000 when examined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. The binding was saturable, irreversible, and inhibited by pyruvate, 2-oxoglutarate, and alpha-cyano-3-hydroxycinnamate, but not by D-lactate… (More)
