Abstract
Wall turnover in M. xanthus was studied by measuring the incorporation and release of meso-diamino[14C]pimelic acid. The rate of turnover was low in vegetatively growing organisms. Following the addition of 0.5 M glycerol to induce myxospore formation in organisms that were labeled for 1 generation in the absence of glycerol, increased rates of incorporation and release were observed before and during cellular morphogenesis. Chloramphenicol inhibited glycerol-induced myxospore formation, but only partially blocked the release of meso-diaminopimelic acid. A mutant, non-inducible by glycerol, was isolated and showed no increased autolytic activity in the presence of glycerol. Parent and mutant strains could be induced to form myxospores by 17 mM phenethyl alcohol, but with both strains there was only a slight increase in meso-diaminopimelic acic release following induction.Keywords
