Because of this small difference, they differ structurally and chemically and are known as chemical isomers because of the different arrangement of functional groups around the asymmetric carbon; both

(Molecular dynamics were discussed in Chapter 3.4: Analyses of Protein Structure.) α-Synuclein (140 amino acids, MW 14,460) is expressed in the brain and presynaptic terminals in the central nervous system but also in more distal neurons and is involved in the regulation of neurotransmitter release and in the synaptic vesicles that ho…

(A) Shown are four resonance structures of the indole ring structure demonstrating that the lone pair of electrons on the nitrogen are involved in the formation of pi-bonds. (B) The imidazole ring structure has one nitrogen (1) that is involved in resonance structures (not shown) and is not available to accept a proton, while the second nitrogen (3) has…

Example: the Z[beta] Domain of the RNA-editing Enzyme ADAR1 (1xmk), shown in the interactive iCn3D model in Figure \PageIndex1. Example: The second SH3 domain from ponsin (2O9S), shown in the interactive iCn3D model in Figure \PageIndex3. Example: Human biliverdin IX beta reductase (1hdo), shown in the interactive iCn3D model in Figure \PageIndex6.
