Abstract:

SsHSP14.1, a novel sHSP from the hyper-thermophilic archaeon Sulfolobus solfataricus (S. solfataricus), is reported herein to function to protect EcoR I from heat-induced inactivation. A predicted salt bridge and hydrophobic interactions were found to be important for this function.

Keywords: Small heat shock proteins (sHSPs), SsHSP14.1, Sulfolobus solfataricus (S. solfataricus), EcoR I, salt bridge, oligomer
