| Primary Identifier | IPR023728 | Type | Family |
| Short Name | HSP20_IbpA |
| description | Small heat shock proteins IbpA associate with aggregated proteins, together with IbpB, to stabilise and protect them from irreversible denaturation and extensive proteolysis during heat shock and oxidative stress. Aggregated proteins bound to the IbpAB complex are more efficiently refolded and reactivated by the ATP-dependent chaperone systems ClpB and DnaK/DnaJ/GrpE. Its activity is ATP-independent[], [].These proteins form homomultimers of about 100-150 subunits at optimal growth temperatures. The conformation changes to monomers at high temperatures or high ionic concentrations. Proteins in this entry belong to the small heat shock protein (HSP20) family. |
