FIG. 4.

Release of cortex fragments from germinating spores. Dormant wild-type (⧫), ΔcwlJ1 (▪), ΔsleL (•), ΔcwlJ1 ΔsleL (○), ΔsleB ΔsleL (Δ), ΔcwlJ1 ΔcwlJ2 (⋄), and ΔcwlJ1 ΔcwlJ2 ΔsleB ΔsleL (×) spores in buffer were sampled for assay of the release of muramic acid following exposure to the germinants l-alanine and inosine. Error bars represent 1 standard deviation of the mean of the results for three independent spore preparations. All points have error bars, but in some cases, these are too small to be visible.
