Abstract excerpt
The Cys127-Cys150 disulfide-bonded loop (L1) of the Torpedo californica Na,K-ATPase beta 1 subunit was substituted with the corresponding loop of the rat beta 1, mouse beta 2, or pig H,K-ATPase beta subunit. All the substituted mutant beta subunits assembled with the Na,K-ATPase alpha subunit in a trypsin-resistant manner. The mutants with L1 from the Na,K-ATPase beta subunit isoforms (rat beta 1 and mouse beta...
