Takahashi Lab
Machine-translated · View original
The lab takes on manufacturing inspired by life, starting from the mechanisms of enzymes and metabolism.
AboutAbout the lab
Manufacturing inspired by life.
The Takahashi Lab studies the metabolic mechanisms of living organisms and the manufacturing that applies them.
The lab has continued its research with "enzymes, metabolism, and their applications" as a consistent set of keywords.
It searches for enzymes in plants and microorganisms that carry out reactions not yet understood, and investigates how they work based on their three-dimensional structures.
Based on the knowledge gained, the lab aims to design new strategies for metabolic engineering.
Key terms
- Enzyme
- A protein-based catalyst that drives chemical reactions in living organisms
- Metabolic engineering
- A technology that rewires how substances are produced in living organisms so that they make a desired compound
- Metabolon
- A protein complex formed by the assembly of multiple enzymes that work in a single metabolic pathway

ResearchResearch themes
The lab aims to uncover the sophisticated metabolic control mechanisms acquired through the evolution of life, and to carry out manufacturing that applies them. It searches for enzymes that carry out unexplained reactions, clarifies how metabolism is controlled by enzyme complexes and the intracellular signaling that regulates the whole system together, and designs new strategies for metabolic engineering.
*Illustrative imageDiscovering and Designing New Enzymes
To adapt to environmental stress, plants and microorganisms produce a wide variety of compounds, and many of these show functions useful to humans. The lab discovers the enzymes that synthesize them, determines their three-dimensional structures, and elucidates the molecular mechanisms of catalysis, and then designs enzymes with altered functions.
*Illustrative imageReassembling Metabolons
A complex formed by multiple enzymes in a metabolic pathway (a metabolon) works to carry out metabolism efficiently in the cell. The lab elucidates the network of interactions among enzymes and among proteins that regulate their activity, and reconstitutes it inside the cells of other microorganisms and plants.
*Illustrative imageControlling Intracellular Signaling
Organisms transmit stimuli received from inside and outside the cell and regulate the amounts of the enzymes and regulatory proteins they need at the level of gene expression. The lab elucidates this complex signaling mechanism and controls it artificially to create plants and microorganisms that can produce and store large amounts of specific compounds.
