title: The association of penicillin-binding proteins with cell elongation and septum formation in Bacillus megaterium.
abstract: Analysis of the penicillin-binding proteins in the membranes from germinated spores of Bacillus megaterium and a filamentous mutant indicated that (a) no specific synthesis of any penicillin-binding protein occurred before or during two relatively synchronous cell divisions, (b) penicillin-binding proteins 1, 3a and 3b may be involved in cell elongation and (c) filamentation of the mutant may be due to a decrease in the concentration of penicillin-binding protein 1.
