Theoretical and Computational Biophysics
Changbong Hyeon works mostly on theoretical and computational studies of biological systems. The emergence of life from individual physicochemical processes of cellular constituents is a major outstanding question in biophysics. The research interests of this group lie in the dynamics of DNA, RNA, and proteins at the single molecule level, as well as in the interactions among these molecules in giant macromolecular complexes such as chromosomes. Studies towards understanding biological phenomena at the systems level are a long-term research goal. Major contributions have recently been made in areas such as: (i) the physical principles underlying molecular motors, (ii) the origin of heterogeneity in bimolecular processes, and (iii) nonequilibrium thermodynamics in living systems.

Title : Signalling networks and dynamics of allosteric transitions in bacterial chaperonin GroEL: implications for iterative annealing of misfolded proteins Journal : PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES. v.373, no.1749, article no.20170182. 2018
Publication(career) NUMBER AUTHOR Thirumalai, D.; Hyeon, Changbong TITLE Signalling networks and dynamics of allosteric transitions in bacterial chaperonin GroEL: implications for iterative annealing of misfolded proteins ARCHIVE FILE JOURNAL PHILOSOPHICAL TRANSACTIONS OF THE ROYAL SOCIETY B-BIOLOGICAL SCIENCES. v.373, no.1749, article no.20170182. 2018 ABSTRACT Signal transmission at the molecular level in many biological complexes occurs through allosteric transitions. Allostery describes the responses of a complex to binding of ligands at sites that are spatially well separated from the binding region. We describe the structural perturbation method, based on phonon propagation in solids, which can be used to determine the signal-transmitting allostery wiring diagram (AWD) in large but finite-sized biological complexes. Application to the bacterial chaperonin GroEL-GroES complex shows that the AWD determined from structures also drives the allosteric transitions dynamically. From both a structural and dynamical perspective these transitions are largely determined by formation and rupture of salt-bridges. The molecular description of allostery in GroEL provides insights into its function, which is quantitatively described by the iterative annealing mechanism. Remarkably, in this complex molecular machine, a deep connection is established between the structures, reaction cycle during which GroEL undergoes a sequence of allosteric transitions, and function, in a self-consistent manner. This article is part of a discussion meeting issue Allostery and molecular machines.

Title : Deciphering kinetic information from single molecule FRET data that show slow transitions Journal : J. Phys. Chem. B. (2015) vol. 119, 6974–6978
Publication(career) NUMBER AUTHOR S. E. Kim, I. -B. Lee, C. Hyeon, S.-C. Hong TITLE Deciphering kinetic information from single molecule FRET data that show slow transitions ARCHIVE FILE JOURNAL J. Phys. Chem. B. (2015) vol. 119, 6974–6978 ABSTRACT Single-molecule FRET is one of the most
powerful and widely used biophysical techniques in biological
sciences. It, however, often suffers from limitations such as
weak signal and limited measurement time intrinsic to single-
molecule fluorescence measurements. Despite several amelio-
rative measures taken to increase measurement time, it is
nearly impossible to acquire meaningful kinetic information on
a molecule if conformational transitions of the molecule are
ultraslow such that transition times (⟨¥ó⟩orig) are comparable to
or longer than measurement times (¥ät) limited by the finite
lifetime of fluorescent dye. Here, to extract a reliable and
accurate mean transition time from a series of short time traces
with ultraslow kinetics, we suggest a scheme called sHaRPer (serialized Handshaking Repeated Permutation with end removal) that concatenates multiple time traces. Because data acquisition frequency f and measurement time (¥ät) affect the estimation of mean transition time (⟨¥ó⟩), we provide mathematical criteria that f, ¥ät, and ⟨¥ó⟩ should satisfy to make ⟨¥ó⟩ close enough to ⟨¥ó⟩orig. Although application of the sHaRPer method has a potential risk of distorting the time constants of individual kinetic phases if the data are described with kinetic partitioning, we also provide criteria to avoid such distortion. Our sHaRPer method is a useful way to handle single-molecule data with slow transition kinetics. This study provides a practical guide to use sHaRPer.

Title : Compaction and Tensile Forces Determine the Accuracy of Folding Landscape Parameters from Single Molecule Pulling Experiments Journal : Phys. Rev. Lett. (2011) 106, 138102
Publication(career) NUMBER AUTHOR Greg Morrison, Changbong Hyeon, Michael Hinczewski TITLE Compaction and Tensile Forces Determine the Accuracy of Folding Landscape Parameters from Single Molecule Pulling Experiments ARCHIVE FILE prl2011.pdf JOURNAL Phys. Rev. Lett. (2011) 106, 138102 ABSTRACT We establish a framework for assessing whether the transition state location of a biopolymer, which can be inferred from single molecule pulling experiments, corresponds to the ensemble of structures that have equal probability of reaching either the folded or unfolded states (Pfold=0.5). Using results for the forced unfolding of a RNA hairpin, an exactly soluble model, and an analytic theory, we show that Pfold is solely determined by s, an experimentally measurable molecular tensegrity parameter, which is a ratio of the tensile force and a compaction force that stabilizes the folded state. Applications to folding landscapes of DNA hairpins and a leucine zipper with two barriers provide a structural interpretation of single molecule experimental data. Our theory can be used to assess whether molecular extension is a good reaction coordinate using measured free energy profiles.
