GENERAL
INFORMATION:
Metallobiochemistry (MBMB 533, three
credit hours) is intended to provide you with a foundation in
modern inorganic biochemistry with specific emphasis on metal-containing
proteins. We will draw upon knowledge of biochemistry, cell biology,
and chemistry to understand some recent scientific problems. You
should be familiar with the Internet and either PC or Mac computers.
Classes meet on Monday and Wednesday afternoons for 75 minute
sessions, unless otherwise specified.
I reserve the right to change or modify
the syllabus.
RESOURCES:
We will use the following textbook and selected articles from the current literature:
You may find it useful to review fundamental
concepts as outlined in any of the recent biochemistry and inorganic
textbooks, including:
- Voet, D., J. G. Voet, and C. W.
Pratt. 1999. Fundamentals
of biochemistry, John Wiley & Sons,
Inc., New York. An upgrade edition of this should soon be available.
- Cotton, F. A., G. Wilkinson, C.
A. Murillo, and M. Bochmann.
1999. Advanced
inorganic chemistry, 6th ed. John Wiley
& Sons, Inc., New York.
We will use the molecular viewing applications
Protein
Explorer, RasMol and Swiss-PdbViewer during this course. See "Chime
Square" for additional information
concerning macromolecular viewing of protein and nucleic acid
structures.
GRADING POLICY:
Your performance in this course will
be based on a combination of examinations and problem sets. Examination
and problem set dates will be announced in class and posted to
the course web site. I reserve
the right to change the date of examinations and problem sets.
There will be no make-up examinations
or problem sets. A valid signed University-approved or medical
excuse must be presented to me as soon as possible if you miss
an examination. In general, only
medical emergencies are considered legitimate excuses. One examination
performance may be offset by the average of your second lowest
examination score and the final examination score.
