FIG. 5.
Effect of decoyinine on transformation efficiency in the relaxed (relA) strain. The relaxed strain (61883) was grown in TF medium containing 20 mM aspartate. Decoyinine alone (2 mM) (circles) or with guanosine (2 mM each) (triangles) was added to the culture at t0 as indicated by the arrow. Samples were taken to determine culture density (A650 [open symbols]) and transformation efficiency (closed symbols). Transformation was performed as described in the legend to Fig. 1. Untreated culture (squares) is shown as a control.
