FIG. 1.

Cellular levels of ggpS mRNA, GgpS protein, and GG in salt-shocked Synechocystis cells. Changes in the cellular contents of ggpS mRNA, GgpS protein, and GG in Synechocystis cells shocked by 684 mM NaCl at time zero were determined. (A and B) Signals for the ggpS mRNA obtained by Northern blot analysis (A) and for the GgpS protein obtained by immunoblot analysis using a specific antibody (B). Lane C, control. (C) Densitometric estimation of the relative mRNA and protein steady-state levels and the absolute amount of GG. Symbols: ▵, ggpS mRNA; □, GgpS protein; ○, GG. rel. units, relative units.
