title: Functional half-life of the exocellular protease mRNA of Bacillus megaterium.
abstract: Functional half-life of the exocellular protease mRNA was determined in in exponentially growing and stationary cells of the asporogenic strain of Bacillus megaterium KM and in the sporogenic strain of B. megaterium 27 during sporulation. No reserve of the protease mRNA could be detected in the cells and the half-lives were determined to be 6--7 min in the exponential and stationary cells of B. megaterium KM and 7.5--8.5 min in B. megaterium 27. The mean half-life of mRNA for cell proteins was determined to be 3.5--4.5 min. Thus, as compared with the mean half-life of mRNA for cell proteins that of mRNA for the exocellular protease is slightly longer.
