Cells damage by protein aggregates is one of the causes of amyloid diseases. This study aimed to explore the structural features of cytotoxic amyloid fibrils and to find strategies to reduce their damaging effect. Bovine carbonic anhydrase B (BCAB) was chosen for this work due to high toxicity of its amyloid fibrils.

The aim of this work was to investigate the effect of amino acid substitutions on the stability of apomyoglobin (ApoMb) amyloids. A study of the amyloid unfolding of ApoMb and its six mutant variants by urea has been carried out.
