All biological processes require the interaction of a number of
macromolecules with each other as well as with small ligand effectors in
order to carry out a particular function in a precise, controlled manner.
In some cases, these interactions are long-lived; however, in most cases,
transient interactions are essential for proper control of biological
function. Even "isolated" ligand-macromolecule interactions and/or
conformational transitions are linked to other binding and/or
conformational transitions, hence all macromolecular interactions are
composed of multiple equilibria. The focus of this course is to introduce
you to the quantitative approaches and logic needed to define these
multiple equilibrium processes and to begin to dissect them in order to
understand the forces involved in stabilizing and regulating the function
of these macromolecules. This requires investigations of the energetics,
thermodynamics (stabilities, affinities), kinetics and mechanism of
binding and enzyme catalysis, including both steady state and transient
(pre-steady state) approaches.
This course will discuss the theoretical principles, logic and approaches
used to study these processes from a quantitative perspective. Topics
will include thermodynamics, multiple binding equilibria, analysis of
binding isotherms, Wyman linkage relationships, cooperativity, allostery,
macromolecular assembly, enzyme catalysis and
mechanism, steady-state and pre-steady state kinetics.
Some techniques used to study binding processes will also be discussed. A
major goal is for the student to use computer simulation and non-linear
least squares methods to aid in the analysis of both equilibrium binding
isotherms and kinetic time courses.
The following books will be used as the main references for the
course, although these will be supplemented with current research
articles.
- Binding and Linkage-Jeffries Wyman and Stanley J. Gill
(University Science Books)
- Kinetics for the Life Sciences-H. Gutfreund (Cambridge University
Press)
Course grades will be based on three exams.
Problem sets will be
handed out every 1-2 weeks but will not be graded.
