Abstract
Although the tertiary structures of mitochondrial cytochromes c (cyts c) seem to be remarkably similar, there are variations in their amino acid sequences, stability and functional properties. GdnHCl-induced unfolding experiments on engineered yeast and horse cyt c were carried out with the aim to to clarify, at molecular level, some aspects concerning the stability of this class of proteins. The results obtained are discussed in the light of the three-dimensional structures of the two proteins.
Keywords: Cytochrome c, guanidinium chloride unfolding, protein stability, circular dichroism, mutagenesis

Therapeutic Proteins and Peptides of Plant Origin
Plants are still the major repository of biologically active substances. In the last two decades, however, natural peptides and proteins of plant origin have gained increasing attention due to their pharmacological activities over a variety of human illnesses, including those mediated by infections and parasitosis and those involving different cellular ...read more
