• The product of an open reading frame (ORF) (called YdbR) identified while analyzing the Bacillus subtilis genome has been classified as an Asp-Glu-Ala-Asp (DEAD) protein, but the biological function and enzymology of YdbR have not been characterized in detail. Here we show that recombinant YdbR-His6 purified from Escherichia coli is an ATP-independent RNA binding protein. It also possesses RNA-dependent ATPase activity stimulated not only by total RNA from B. subtilis but also by an RNA that is irrelevant to that of B. subtilis. Functional analysis indicated that the growth rate of a ΔydbR mutant strain of B. subtilis was reduced as compared with that of the wild type not only at 37 °C, but more severely at 22 °C.
