Biomolecular Dynamics Lab
Machine-translated · View original
The lab studies how proteins fold at the single-molecule level.
AboutAbout the lab
Life science research centered on the keyword "protein folding"
The Biomolecular Dynamics Lab conducts experimental research to clarify the mechanisms by which proteins fold into specific structures.
A protein is a polymer made of amino acids strung together like beads, and it performs its function by folding into a defined structure.
Using original experimental instruments, the lab takes on the "protein folding problem," which asks why proteins can fold almost without error in such a short time.
On the lab's website, it is introduced under the name "Takahashi (Satoshi) Lab."
Key terms
- Single-molecule observation
- A method of studying molecules one at a time. Changes in protein structure are followed through changes in fluorescence intensity
- Phage display
- A method in which proteins are displayed on the surface of phages so that those with desired properties can be selected
- Time resolution
- The shortest time interval over which changes can be distinguished. The shorter it is, the faster the motions that can be followed
- Molecular dynamics simulation
- A computation that tracks the motions of atoms and molecules on a computer

ResearchResearch themes
From an experimental standpoint, the lab works on the "protein folding problem": how proteins, which carry out the functions of life, fold into specific structures. To capture folding motions in as much detail as possible, it develops original experimental instruments, including a new instrument that detects folding at the single-molecule level.

By combining phage display with a fluorescence observation instrument, the lab is trying to establish a method for selecting proteins with desired properties from a wide variety of sequences. It is developing an instrument that recovers the sample after detecting a single-molecule signal.
*Illustrative imageSingle-Molecule Observation of Fast Protein Motions
The lab is developing an instrument that continuously tracks changes in the fluorescence intensity of single molecules with a time resolution of tens of microseconds. This is thought to lead to experimental verification of protein motions predicted by molecular dynamics simulations.
