Enzyme Activity
A phosphodiesterase is an enzyme that catalyzes the hydrolysis of phosphodiester bonds, for instance a bond in a molecule of cyclic AMP or cyclic GMP.
An enzyme that plays an important role in the repair of oxidative DNA damage is the 3'-phosphodiesterase.
During the replication of DNA, there is a hole between the phosphates in the backbone left by DNA polymerase I. DNA ligase is able to form a phosphodiester bond between the nucleotides.

Famous quotes containing the word activity:
“The mob is man voluntarily descending to the nature of the beast. Its fit hour of activity is night. Its actions are insane like its whole constitution. It persecutes a principle; it would whip a right; it would tar and feather justice, by inflicting fire and outrage upon the houses and persons of those who have these. It resembles the prank of boys, who run with fire-engines to put out the ruddy aurora streaming to the stars.”
—Ralph Waldo Emerson (1803–1882)
