Abstract excerpt
To understand the role of cysteine (SH) residues in the folding of hen ovalbumin (OVA), SH-mutated OVAs, in which each SH residue was replaced by alanine (C11A, C30A, C367A, and C382A), were prepared. SDS-PAGE analysis under non-reducing conditions showed that the C11A and C30A mutants produced a disulfide (SS) isomer in addition to a protein with a native SS bond (Cys73-Cys120). The susceptibility to elastase...
