Motivation:
DNase II is an endodeoxyribonuclease involved in apoptosis and essential for the mammalian development. Despite the understanding of biochemical properties of this enzyme, its structure and relationships to other protein families remain unknown.
Results:
Using protein fold-recognition we found that DNase II exhibits a catalytic domain common to the phospholipase D superfamily. Our model explains the available experimental data and provides the first structural platform for sequence-function analyses of this important nuclease.

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
