Antigenic relationships between plasma membrane ATPases of two different yeasts, Candida tropicalis and Schizosaccharomyces pombe

Abstract

Antibodies raised against purified plasma membrane ATPase from the yeast S. pombe inhibit the plasma membrane-bound ATPase of another yeast, C. tropicalis. The kinetic constants, Vm and Km, of the ATPases are both modified by the antibodies. These results show antigenic relationships between the plasma membrane ATPases belonging to the two yeast genera.
