Active Site

In biology the active site is part of an enzyme where substrates bind and undergo a chemical reaction. The majority of enzymes are proteins but RNA enzymes called ribozymes also exist. The active site of an enzyme is usually found in a cleft or pocket that is lined by amino acid residues (or nucleotides in ribozymes) that participate in recognition of the substrate. Residues that directly participate in the catalytic reaction mechanism are called active site residues.

Famous quotes containing the words active and/or site:

    Photography suits the temper of this age—of active bodies and minds. It is a perfect medium for one whose mind is teeming with ideas, imagery, for a prolific worker who would be slowed down by painting or sculpting, for one who sees quickly and acts decisively, accurately.
    Edward Weston (1886–1958)

    The present hour is always wealthiest when it is poorer than the future ones, as that is the pleasantest site which affords the pleasantest prospects.
    Henry David Thoreau (1817–1862)
