Incomplete Protein Digestion

Caption

Chien and Vass's recent work shows that in some bacteria, short forms of a specialized replication factor, the protein DnaX, are made by proteolysis, an unexpected finding and evidence of convergent evolution. Two forms are generated through radically different mechanisms, suggesting for the first time that both long and short forms are required for all bacteria.
