Theoretical Study on Catalysis by Protein Enzymes and Ribozyme

Principal Investigator: Martin Karplus, Harvard University Research Objectives The goal of this project is to develop a greater understanding of the mechanisms involved in enzyme catalysis and related protein functions. We are studying two types of enzymes: proteins and a nucleic acid (hammerhead ribozyme). Computational Approach  For active-site models in the gas phase, ab initio or density functional (DFT) calculations are used. A few calculations with continuum dieletric models are… Read More »

Theoretical Study on Catalysis by Protein Enzymes, Ribosome, and Molecular Motors

Principal Investigator: Martin Karplus, Harvard University Research Objectives This project's goal is to develop a greater understanding of the mechanisms involved in enzyme catalysis and related protein functions. We are studying the protein enzymes chorismate mutase, flavoxireductase, and aminopeptidase, and a nucleic acid enzyme, the hammerhead ribosome. We are also studying another class of enzymes known as molecular motors, which play important roles in bioenergy transduction and gene… Read More »
