Abstract

A novel 18-kDa heat shock protein, HrpA, has been identified from Mycobacterium bovis BCG. HrpA was rapidly synthesized in membrane and ribosome fractions but not in the cytoplasmic fraction under heat shock stress. HrpA bound tightly to 70S ribosomes, mainly in 30S subunits. HrpA might be involved in the initiation step of translation at high temperature.
