Web. Web. Based on structure, proteins can be classified into the following types: Fibrous proteins: In this structure of a protein, the polypeptide chain runs parallel and held together with the help of hydrogen and disulphide bonds and thus forming a fiber-like structure called fibrous proteins. These are insoluble in water.. Web. Proteins have four levels where it can exist: primary, secondary, tertiary and quaternary structure . Primary Structure refers to the order/ sequence of amino acid residues within a polypeptide backbone while Secondary Structure involves hydrogen bonding between atoms which causes folding or bending such as Alpha Helix or Beta Strand formation .. Web. Web.

The two main types of secondary structure are the α-helix and the ß-sheet. Tertiary Structure. This describes the three-dimensional shape of proteins. This structure is formed as a result of the bonds between the side groups (R groups) of amino acids, which bend the different polypeptide chains and give protein its unique shape.. Web. Web. SH3 domains have a characteristic 3D structure (Figure 4). They occur in a diverse range of proteins with different functions, including adaptor proteins, phosphatidylinositol 3-kinases, phospholipases and myosins. Figure 4 Structure of the SH3 domain. An example of a protein that contains multiple SH3 domains is the cytoplasmic protein Nck.. Web. The primary protein structure is the sequence of amino acids in a polypeptide chain. This sequence is determined by the DNA, more precisely by specific genes. This sequence is essential because it affects both the shape and the function of proteins. If only one amino acid in the sequence is changed, the shape of the protein changes.. The primary protein structure is the sequence of amino acids in a polypeptide chain.
