"If it wasn't the product we were looking for ... The next step is to obtain real 3-D crystal structures of enzyme-substrate complexes, using the National Synchrotron Light Source at Brookhaven ...

The natural protein, known as CelOCE, was developed at the Brazilian Center for Research in Energy and Materials and is ready ...

Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. The substrate goes through a chemical reaction and changes into a new molecule ...

Once the substrate fully locks in and in the ... For instance, if an enzyme makes too much of a product, then the body needs a way to reduce or stop the production. Enzymes play a large part ...

Since it sometimes takes several catalysts and steps to produce the desired product ... to improve the substrate materials for the enzymes. "The silicate substrates we have been using so far ...

The lock and key model explains how enzymes work: The enzyme is like a "lock". The substrate (the molecule it reacts with) is like a "key" that fits into the lock. Each enzyme is specific and acts ...

"We've identified a metalloenzyme that enhances cellulose conversion through a previously unknown mechanism of substrate binding ... allowing other enzymes to do the conversion. Its role isn't to ...
