Cell wall autolysis in log phase cells of Micrococcus lysodeikticus (luteus).
Log phase cells of Micrococcus lysodeikticus (luteus) IFO 3333 autolyzed when incubated at 37 C in 0.01 M sodium-phosphate buffer pH 7.5. The enzyme involved in the autolysis was recovered mainly in an aqueous phase from cytoplasmic membranes and cytoplasmic materials treated with n-butanol, and proved to be an N-acetylmuramyl-L-alanine amidase. The autolysis of log phase cells suspended in autolyzing buffer was depressed by the addition of trypsin to the buffer.
