RESUMO
The relationship between conditions which permit or inhibit cell lysis and those which promote phospholipid hydrolysis in Neisseria gonorrhoeae was investigated. Suspension of exponential-phase gonococci in buffer in the absence of divalent cations resulted in autolysis but not in phosphlipid hydrolysis. The addition of Ca2+ or Mg2+ to the buffer inhibited autolysis and markedly stimulated the hydrolysis of phosphatidylethanolamine. Incubation of cells in buffer at pH 6 inhibited both autolysis and phospholipid hydrolysis.
