Expression of the archaeal promoters in the E. coli ex vivo reporter system.

a.Values are shown as relative light units and the average of at least three independent readings.b.Genes and operons shown in each reporter plasmid are listed in Table S1.c.Fold difference of the luciferase activity are calculated from those determined for E. coli strain carrying plasmid pairs of FilR1-vacant p184 plus pOx-lux over that of the strain carrying pOx-lux alone (+p184/−), strain with FilR1 plus pOx-lux over that with pOx-lux alone (+pFilR1/−), and strain with FilR1 plus pOx-lux over that with FilR1-vacant p184 plus pOx-lux (+pFilR1/+p184).
