Abstract
The crystal structure of the dimerization domain of the V(D)J recombin ation-activating protein, RAG1, was solved using zinc anomalous scatte ring. The structure reveals an unusual combination of multi-class zinc -binding motifs, including a zinc RING finger and a C2H2 zinc finger, that together form a single structural domain. The domain also contain s a unique zinc binuclear cluster in place of a normally mononuclear z inc site in the RING finger. Together, four zinc ions help organize th e entire domain, including the two helices that form the dimer interfa ce.
