Abstract Digestion of deoxyribonucleoproteins (DNP) of Gram-negative bacteria by micrococcal nuclease and by Ca++- and Mg++-activated bacterial endonuclease followed by electrophoresis revealed a group of DNP-fragments of discrete size in each species, as well as large nuclease-resistant DNP fractions. The approximate molecular weight of the smallest bacterial DNP fragment was estimated to be 120–140 base pairs. At least two cationic proteins, with electrophoretic mobility close to that of eukaryote histone H4 were discovered in the DNP of each species of bacteria. The presence of a universal principle of regular subunitary DNP structure in bacteria is postulated.
