Cel7A cellulase enzymes (gold) are inhibited when breaking down cellulose (green) by the product, cellobiose, at both the “front door" (1) and “back door" (2) of the Cel7A tunnel, and by two other ...

A new microscopy method enables researchers to visualize the activity of the enzymes caspase-3 and alkaline phosphatase in various biological samples (Nat. Methods 2024, DOI: ...

Hedgehog proteins are some of the most important molecules in biology. These proteins help regulate cell growth, specialization, and patterning in the development of embryos by acting as messengers ...

The enzyme transhydrogenase plays a central role in regulating metabolic processes in animals and humans alike. Malfunction can lead to serious disorders. For the first time, structural biologists ...

Proteins are the building blocks of all living things. A vast amount research takes place on how these proteins are made and what they do, from enzymes that carry out chemical reactions to messengers ...

UNIVERSITY PARK, Pa. -- The construction of a new multimodal optical microscope, SCATTIRSTORM, that could enable more efficient bioenergy production, is the focus of a three-year, $1.5 million, U.S.

A new microscopy method enables researchers to visualize the activity of the enzymes caspase-3 and alkaline phosphatase in various biological samples (Nat. Methods 2024, DOI: ...

Structural biologist Stephen Long is using cryogenic electron microscopy to study proteins at the atomic level. Hedgehog proteins are some of the most important molecules in biology. These proteins ...
