For example, they perform a necessary function ... too high or if the environment is too acidic or alkaline, the enzyme changes shape; this alters the shape of the active site so that substrates ...

Changes in pH alter the shape of an enzyme’s active site. Different enzymes work best at different pH values. The optimum pH for an enzyme depends on where it normally works. For example ...

The three-dimensional shape of a protein determines its function ... the protein that makes up hair and nails Enzymes Catalyse biological reactions ATPase: catalyses the breakdown of ATP and ...

In biology, enzymes have evolved over millions of years to drive chemical reactions. Scientists from the Max Planck Institute ...

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 ...

In fact, the enzyme appears to be unique in its ability to change its shape—and its job in cells—without overhauling its basic architecture. New research led by scientists at The Scripps ...

An online group of gamers has correctly deduced the structure of an enzyme that AIDS-like viruses ... The function of the protein changes with the shape it takes. Gamers bring a different ...
