Abstract
A mutant of Escherichia coli, in which signal peptidase I synthesis can be regulated, was constructed. The mutant was used to study the effects of signal peptidase I limitation on the synthesis and efficiency of processing of two proteins: the periplasmic E. coli TEM-beta-lactamase and Bacillus licheniformis alpha-amylase, which also accumulates in the periplasm of E. coli. Signal peptidase I limitation resulted in reduced rates of processing of pre-beta-lactamase and in strong inhibition of synthesis of alpha-amylase. The data suggest that beta-lactamase is processed post-translationally and that an intimate relationship exists between the synthesis and processing of alpha-amylase.Entities:
