Popis: | HrpA was found as a ribosome-associated protein which appeared in heat-stressed Mycobacterium bovis Bacillus Calmette-Guérin. Here, we have studied the function of HrpA in vitro. HrpA is a heat shock protein belonging to a small heat shock protein family. The putative molecular mass was 17784.86 kDa. Recombinant HrpA formed large complexes of nonamer or dodecamer. HrpA prevented the aggregation of enzymes under heat shock conditions, and it formed stable complexes with partially denatured enzymes. HrpA was induced temporarily by oxygen repletion after anaerobic condition. |
