Abstract

The level of three peptidoglycan hydrolases was determined in the mother cell compartment and forespores of Bacillus sphaericus. Vegetative and sporulating cells contained in LD-carboxypeptidase active only on the vegetative cell wall peptidoglycan, and we have previously shown that sporulation is accompanied by the production of two new enzymes active only on the spore cortex peptidoglycan. These gamma-D-glutamyl-meso-diaminopimelate endopeptidase and a meso-diaminopimelate-D-alanine dipeptidase. The LD-carboxypeptidase activity appeared to be located in the membranes of both the mother cells and forespores. Endopeptidase activity was located in the integument fraction of the forespores, and the dipeptidase activity was only found in the forespore cytoplasm. These different locations comply with the probable different functions of these enzymes.
