  Active site - Wikipedia, the free encyclopedia
The active site of an enzyme is the binding site where catalysis occurs.
The structure and chemical properties of the active site allow the recognition and binding of the substrate.
The active site is usually a small pocket at the surface of the enzyme that contains residues responsible for the substrate specificity (charge, hydrophobicity, steric hindrance) and catalytic residues which often act as proton donors or acceptors or are responsible for binding a cofactor such as Pyridoxal, Thiamine or NAD.

 active site of an enzyme   (Site not responding. Last check: 2007-10-06)
The active site of the enzyme is the place where the substrate binds and at which catalysis occurs
In the induced fit model of enzyme-substrate binding, the shape of the active site of the unbound enzyme is not the exact complement of the shape of the substrate.
After binding of the enzyme to the substrate is initiated, a conformational change in the shape of the active site which results in a new shape of the active site that is complementary to the shape of the substrate.

 Cerius2·Ludi - Working with the Protein Active Site Viewer
The Active Site Viewer allows you to view and analyze both the structure and the environment of bound ligands and active sites.
To define an active site by expanding a volume around a ligand you must first select the ligand by either picking a non-protein residue from the NON_PROTEIN RESIDUES list box, or by selecting all atoms in a ligand that is as separate model that has been positioned into the active site.
Active Site Viewer no longer has a command to recombine the template ligand with the protein.

The Active Directory uses sites to determine which IP subnets are considered "well-connected" in your environment.
By your site definition, the Active Directory assumes that the IP subnets within a site are well connected and that bandwidth is considered freely available and inexpensive.
After the Active Director understands how your sites are linked together, you can then begin to implement control features that can help you find the balance between accurate data and latency that is right for your organization.

Sites are classified into either PTM, post-translational modification; AS, active site or BS, binding site.
Many of the PTM sites have low specificity and the number of proteins recognised by the sequence signatures cannot be displayed.
Active sites are best known as the catalytic pockets of enzymes where a substrate is bound and converted to a product, which is then released.
