Abstract
A definite change in the forms of DNA ligase appears when the axolotl egg enters cleavage. Sucrose gradient and phosphocellulose chromatography show that the a 6S form of DNA ligase exists before division, i.e. in unfertilised and fertilised egg, and a 8.2S form is present at the first division. N-ethylmaleimide sensitivity and heat stability are different for the two forms. The possible significance of this early change is discussed.Entities:
