이론 및 계산 생물물리
현대과학에서 생명현상에 대한 탐구노력과 그에 따른 성과들은 실험기술의 발달과 더불어 급격하게 증가하였다. 최근에는 생체분자의 구조변화 및 그에 따르는 생물학적 기능의 동역학을 단일분자 수준에서 직접 관찰하는 것이 가능해지면서, 고전적인 생물학 교과서의 지식을 넘어 물리화학 및 통계역학적 사고에 입각한 좀더 미시적이고도 근본적인 접근법이 생물학 연구에 필요한 시점에 도달하였다. 현창봉 교수의 이론 및 계산 생물물리 연구실에서는 생물계를 복잡계의 하나로 보고, 생체고분자의 동역학 및 상호작용을 분자모형을 이용한 시뮬레이션과 통계역학적인 방법을 통해서 연구하고 있다. 세부연구주제에는 다음과 같은 것들이 있다.
1. 역학적인 힘을 가했을 때 생분자의 반응.
2. RNA와 단백질의 자기조직화 과정.
3. 분자나노모터의 작동원리 이해.
4. 역학적 힘을 이용한 단일분자 실험방법론에 대한 고찰.
5. 다차원에너지공간 특성의 측정과 데이타 해석 방법 제시.
6. 고분자물리.
7. Allostery.
위의 세부적 연구주제들과 더불어 생명현상에 대해 시스템레벨에서의 포괄적인 이해를 갖는 것이 연구실에서 추구하는 궁극적인 목표이다.

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
논문 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
논문 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 (⟨τ⟩orig) are comparable to
or longer than measurement times (δt) 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 (δt) affect the estimation of mean transition time (⟨τ⟩), we provide mathematical criteria that f, δt, and ⟨τ⟩ should satisfy to make ⟨τ⟩ close enough to ⟨τ⟩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
논문 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.
