[Analysis of the structure of Bacillus brevis neutral proteinase and its biosynthesis in Bacillus subtilis cells].

Amino acid sequence of neutral metalloprotease from Bac. brevis has been compared with that of Bac. amyloloquefaciens, Bac.

[Stability of normal, abnormal and recombinant proteins in Escherichia coli strains deficient for intracellular proteinase La--the product of the lon gene].

Escherichia coli Lon-mutants deficient in intracellular protease La have been isolated. The rate of degradation of normal cellular proteins was 1.5-2-fold lower in Lon-mutants as compared with that of the wild type strain.
