Not only in a biotechnological view but also to obtain a fundamental understanding of the folding of complex beta-sheet proteins, it is important to investigate the structure formation of antibodies, their fragment and domains. In this thesis, the constant domains CH2 and CH3 of the antibody MAK33 were compared. Therefore, intensiv studies regarding structure, stability and folding were performed. They showed, that in spite of similar sequence and structure stability and folding significantly differ from each other. Stability depends on the presence of the intra-molecular disulfide bridge. Moreover, the folding process is influenced by both this covalent bond and the trans-cis isomerization of Xaa-Pro bonds. It could be shown that antibody domains can adopt different conformation under different conditions which are comparable regarding their stability.
