In silico Simulation and Modeling of Protein and Small Molecule Structures
Modern computational methods give novel insight into the structure and function of proteins and enzymes. Two examples of visual output from these computational methods are given below.
Left Panel: A short model peptide modified at a cysteine residue with a stable free radical nitroxide probe. Protein modifications such as this one allow the determination of the details of a protein's structure and function.
Right Panel: Another modeled free radical spin probe. The peptide backbone is shown as a purple line. The residue is shown in colors coded for each atom type (Dark Blue = nitrogen, Light Blue = carbon, Red = oxygen, White = Hydrogen, Yellow = sulfur).
Left Panel: Model of a transcriptional control protein bound to its specific DNA binding sequence. Protein DNA interactions like this are the common starting point for the control of gene expression. This structure of the 434 Cro protein complexed with a 20 base pair piece of DNA containing its Operator OR1 was determined by A.Mondragon & S.C.Harrison (protein data bank accession code 3cro). The secondary structure of the protein is shown schematically in gray; the DNA double strands are shown in colors coded for each atom type (see left panel - Orange= phosphorous).
Right Panel: Model of a multidrug resistance pump from humans showing a steric conflict between a substrate and a drug. These proteins are important in cancer and viral chemotherapies. The purple rods and yellow ribbons show the enzyme and the drug and substrate molecules are shown with van der Waal's spheres.
