Enzymes which contain regions to which small, regulatory molecules (cf.
effector) may bind in addition to and separate from
substrate binding sites. On binding the
effector, the catalytic activity of the enzyme towards the substrate may be enhanced, in which case the
effector is an
activator, or reduced, in which case it is an
inhibitor.
