  • Title: Disappearance of glyceraldehyde 3-phosphate dehydrogenase from erythrocyte membrane by hemolysis with thermostable direct hemolysin of Vibrio parahaemolyticus or Vibrio cholerae El Tor hemolysin.
    Author: Zhang D, Honda T.
    Journal: Microbiol Immunol; 1999; 43(3):303-5. PubMed ID: 10338202.
    Abstract:
    It is believed that the thermostable direct hemolysin (TDH) of Vibrio parahaemolyticus and El Tor hemolysin (ETH) of Vibrio cholerae damage erythrocytes and other cells by acting as pore-forming toxins. In this study, we found that a protein band with a molecular weight of 37,000 daltons specifically disappeared from erythrocyte membrane after hemolysis by TDH and ETH, but not after hypotonic hemolysis. The 37 kDa band was identified as glyceraldehyde 3-phosphate dehydrogenase (G3PD), a glycolytic enzyme, based on N-terminal 14 amino acid sequencing. The role of G3PD in hemolysis is discussed.
