The mtrB gene of Bacillus pumilus encodes a protein with sequence and functional homology to the trp RNA-binding attenuation protein (TRAP) of Bacillus subtilis.
The mtrB gene from Bacillus pumilus encodes a 76-amino-acid polypeptide with 77% identity to the trp RNA-binding attenuation protein (TRAP) from Bacillus subtilis. B. pumilus TRAP binds trp leader RNA from either B. subtilis or B. pumilus in a tryptophan-dependent manner. Altering threonine 52 to alanine eliminated RNA-binding activity of B. pumilus TRAP.
