Peptidoglycan of a gram-negative stalked bacterium, Caulobacter crescentus CB13, contained alanine, diaminopimelic acid, and glutamic acid, in molar ratios of 2 : 1 : 1. The amino acid compositions of peptidoglycans isolated from cultures enriched in swarmer and stalked cells, and from a stalk-less mutant were similar. This finding conflicts with a previous observation that swarmer peptidoglycan does not contain diaminopimelic acid (Goodwin and Shedlarski (1975) Arch. Biochem. Biophys. 170, 23-36). It appears that, despite the morphological differences, the Caulobacter cells all contain a similar peptidoglycan in the cell wall.
