Abstract A competence factor (CF) from Rhizobium japonicum was partially purified to 43 fold on Sephadex G-100. This CF preparation was sensitive to heat, trypsin and pronase, was resistant to DNase 1, RNase A and lysozyme. It had an approximate mol. wt. of 82,000. Osmotic shock treatment of competent cells revealed that the CF is located in the periplasmic region of the cell.
