a. Draw the reaction that takes place when a disulfidebond is formed. What conditions are required for this to occur?What is the major role of disulfide bonds? What kinds of proteinsnormally have disulfide bonds? Where do you expect to findribonuclease, the enzyme used in Anfinsen’s famousexperiment?
b. Ohm loops are also considered secondary structure.How does their structure differ from other secondary elements? Whatfunction do these loops serve? Where are loops typically found onproteins?
c. The fatty acid binding protein and bacterial porinexist in completely different environments, one hydrophobic and onehydrophilic, and also transport molecules with the oppositeproperties. Describe the structural features these proteins have incommon and how this structure can serve these two opposingroles.
