Suite of LOs on Biomimetic Modeling
This suite of activities can be used as a unit exploring the use of small molecule models and biophysical techniques to illuminate complicated biomolecules. The Parent LO: Modeling the FeB center in bacterial Nitric Oxide reductase is a short, data-filled and well-written article that is approachable with an undergraduate's level of understanding.
The Structure and Function of Transferrin
Description
These Five Slides About examine the structure and function of the iron binding and transport protein transferrin. Students learn that transferrin also acts as an iron buffer and as a potential antimicrobial agent. The structure of the protein is explored in detail; it consists of a single polypeptide (80kDa) folded into two lobes, each of which can bind a single iron in a high affinity region. Changes in the protein as a result of iron uptake is discussed. The iron binding region and the requirement of a bidentate synergistic anion (carbonate) are examined.
Introduction to Photoinduced Electron Transfer
Description
This 5 slides about will introduce students to the concept of photoinduced electron transfer. These slides go over the energics of photoinduced electron transfer, which implements basic concepts of photochemistry and electrochemistry. The photoinduced electron transer properties of ris-(2,2'-bipyridine)-ruthenium(II) is used as an example.
Modeling post-translational modification in cobalt nitrile hydratase with a metallopeptide from Anne Jones
Description
In this literature discussion, students read a paper about a cobalt metallopeptide that imitates the active site of the enzyme nitrile hydratase. Specifically, the model complex is oxidized by air to produce a coordination sphere with both cysteine thiolate and sulfinic acid ligands, much like the post-translationally oxidized cysteine ligands in the biological system.
Cobalt Schiff Base Zinc Finger Inhibitors
Description
This is a literature discussion based on the paper “Spectroscopic Elucidation of the Inhibitory Mechanism of Cys2
The Synthesis and Characterization of a trans-Dioxorhenium(V) Complex
Description
This experiment involves the preparation of a key starting reactant in high purity and yield for an ongoing research project, specifically for the development of potential photodynamic therapy (PDT) agents. The students synthesize [ReO2(py)4]Cl.2H2O using standard inorganic synthesis techniques. The students visualize the vibrations and electronic properties (e.g. molecular orbitals) of the compound using output files generated from density functional theory (DFT).
Inorganic Spectroscopy Introduced Using an Interactive PhET Simulation (Part 2)
Description
This is the second part of a two-day class discussion on molecular and inorganic spectroscopy. In this activity, upper level students learn about spectroscopic tecniques used in inorganic chemistry and then devise an experiment to follow the progress of a hypothetical reaction. The activity also prepares students for the inorganic laboratory "Linkage isomerism of nitrogen dioxide" in which infrared spectroscopy is used to monitor changes to the N-O vibrational stretch upon coordination to a metal.
Practical MCD Tutorial- How to collect MCD Data- Lehnert Lab
Description
Nicolai Lehnert's group recently shared this video they made for the Penn State Bioinorganic Workshops on Youtube. This is a great practical demonstration of how MCD data is actually collected.
5 (or 6) Slides about Biophysical Techniques
Description
This Five Slides About was prepared specifically for the 2014 IONiC/VIPEr workshop Bioinorganic Applications of Coordination Chemistry held at Northwestern University July 13-18, 2014.
