Properties of the nucleases of mollicutes.
Extracts of the Mollicutes Acholeplasma equifetale, Acholeplasma laidlawii B, Mycoplasma arthritidis. Mycoplasma pulmonis, and Mycoplasma pneumoniae had DNase and endonuclease activity. A. laidlawii B had at least two peaks of DNase activity in sucrose gradients with sedimentation coefficients of 3.1S and 4.3S. These fractions also had endonuclease activity with different substrate specificities. A. laidlawii B may have more than two peaks of endonuclease activity in sucrose gradients.
