Tritiated Digoxin Binding to (Na+ + K+)-Activated Adenosine Triphosphatase: Possible Allosteric Site

Abstract
In the report, "Tritiated digoxin binding to (Na+ + K+)-activated adenosine triphosphatase: possible allosteric site" by Arnold Schwartz et al. (p. 323, 19 Apr.), the opening parentheses of line 6, column 3, has been omitted. The line should read "(Na+ + K+)-activated adenosine triphosphatase. . . ." The last line of paragraph 1 should read "K+-dependent phosphatase reaction (6)" and not ". . . phosphate reaction. . . ."
