Overview of RPP5/At-RSH1 interactions and (p)ppGpp synthetase domain-containing proteins. (A) Domain structure of RPP5 and interaction of RPP5 bait constructs with At-RSH1 (RSH1–18) in the yeast two-hybrid assay. β-Galactosidase ± SD in Miller units are averages from two replicates with three transformants. (B) Domain structure of At-RSH1, hydrophilicity analysis, and the five groups with At-RSH1 clones. R5-int, RPP5 interaction domain; TM, two transmembrane segments. (C) Domain structure of At-RSH2 and At-RSH3 with the (p)ppGpp synthetase domains aligned relative to that of At-RSH1, E. coli RelA (GenBank J04039) and SpoT (M24503), and S. coelicolor RelA (X87267).
