A dipeptidase activity on ms ‐A 2 pm‐ d ‐Ala and l ‐Lys‐ d ‐Ala was found in sporulating cells of Bacillus sphaericus 9602. The specific activity of this enzyme was low during the growth cycle and showed a rapid increase throughout sporulation. Values in the dormant spores were 1.3‐fold higher than those found in cells late in sporulation and 20‐fold higher than those found in log‐phase cells.
