Active site

Active site
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.

active site: the portion of an enzyme that interacts with the substrate.
active transport: the movement of molecules across a membrane from a region of low concentration to a region of high concentration that requires the expenditure of energy (ATP).

Cartoon showing the active site of an enzyme.
Most enzymes are larger than the substrates they act on and only a very small portion of the enzyme, around 10 amino acids, comes into direct contact with the substrate(s).

Such information will be critical to our understanding of the "relative rigidity" of the active site of Pol b during catalysis, i.e., does the active site remodel in the presence of either the correct or incorrect nucleotide triphosphate?

The drastic displacement of the acyl-linked protease grossly disrupts its active site and gives an overall loss of 40% of ordered structure.

Noncompetitive Inhibition occurs when the inhibitory chemical, which does not have to resemble the substrate, binds to the enzyme other than at the active site. Lead binds to SH groups in this fashion.

A process that reduces the yield of photosynthesis, because the active site of rubisco accepts O2 in place of CO2 and generates no ATP.

At lower concentrations, the active sites on most of the enzyme molecules are not filled because there is not much substrate. Higher concentrations cause more collisions between the molecules.

This molecule fits into the active site of the ABL protein preventing ATP from binding there. Without ATP as a phosphate donor, the ABL protein cannot phosphorylate its substrate(s).

Motif: A recurring pattern of short sequence of DNA, RNA, or protein, that usually serves as a recognition site or active site. The same motif can be found in a variety of types of organisms.

About 90% of inteins (protein introns) contain domains whose amino acid sequences are about 34% similar to those of the HO site-specific endonuclease. They also have a 12 residue sequence closely similar to the residues of the HO active site.
