Note both the high structural homology of the two proteins and the very close overlap of the positions of the disulfide moieties. Although it is clear that the main members of the OsmC family act as peroxidases, it is worth noting that the amino acid sequence of OSMCMp, (see Fig. 1) ...
Proteins are polymers of How does DNA-binding protein bind to DNA? Draw the skeletal structure for a 1-chloro-2-fluoroethane polymer with 3 monomers. What are the polymers of fatty acids? What monomers are found in DNA and RNA? How do hydrogen bonds stabilize protein structure? What are ...
What are the organic functional groups in amino acids that bond with each other to form proteins? The side chains of glutamic acid (P_k = 4.3) and arginine (P_k = 12.5) can form an ionic bond under certain conditions. Draw the relevant portions of th...

1. Reports suggest that proteins have evolved to place arginine residues at their surfaces to help stabilize their structures (Strub et al. 2004). Arginine is considered the most favored amino acid due to its capacity to interact in different conformations, its side chain length, and its ...
Chapter 5 The Three-dimensional Structure of Proteins 1. Early studies on the peptide (protein) structure 1.1 The peptide (O=C-N-H) bond was found to be shorter than the C-N bond in a simple amine and atoms attached are coplanar. ...

Proteins are formed when a covalent, peptide bond links the carboxyl group (-COOH) of one amino acid to the amino group (-NH2) of another (C). The resulting thread-like backbone of every protein contains a series of rotatable bonds (ϕ and Ψ) within this peptide chain (D). The ...
