MIT scientists used light to control how a starfish egg cell jiggles and moves during its earliest stage of development.

Engineered starfish oocytes shape-shift in response to light, may enable the design of synthetic, light-activated cells for ...

Researchers use light stimuli to shape cells and develop a model that explains the mechanisms – with implications for synthetic biology.

The researchers observed that light activated the enzyme, causing predictable cell movements. For example, specific light ...

For example, structural proteins maintain cell shape, akin to a skeleton, and they compose structural elements in connective tissues like cartilage and bone in vertebrates. Enzymes are another ...

Different enzymes contain up to 20 different amino acids linked together to form a chain which then folds into the globular enzyme shape. Enzymes have active sites which only match specific ...

In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of the substrate molecule, or molecules. This is essential to the enzyme being able to work.

MIT scientists have discovered a way to control the movements of starfish cells using light, which could have biomedical applications.

Enzymes are proteins that can change shape and therefore become active or inactive. An activator molecule (green pentagon) can bind to an enzyme (light green puzzle shape) and change its overall ...
