The fоllоwing is аn excerpt frоm а recent scientific publicаtion:“For most proteins in the genome databases, function is predicted via sequence comparison. In spite of the popularity of this approach, the extent to which it can be reliably applied is unknown. We address this issue by systematically investigating the relationship between protein function and structure. We focus initially on enzymes functionally classified by the Enzyme Commission (EC) and relate these to structurally classified domains the SCOP database. We find that the major SCOP fold classes have different propensities to carry out certain broad categories of functions.” According to the excerpt, which structural classification is most predictive of enzyme functional categories?

In your answer, be sure to define both concepts and describe their influence on bond returns. Then, discuss at least two practical strategies a portfolio manager can use to manage interest rate risk. Finally, describe how you would communicate these risk management measures to clients concerned about rising rates.
