Abstract excerpt
When Tyr-307 of the beta subunit of F1-ATPase from a thermophilic Bacillus strain PS3 is replaced by cysteine and expressed in Escherichia coli cells, about a half population of the mutant beta subunit are labeled by Coenzyme A at Cys-307 through a disulfide bond which is cleavable by reducing treatment. The mutant beta subunit can be reconstituted into the alpha 3 beta 3 complex of which ATPase activity is...
