Retroviral integrase, an essential enzyme for replication of human immunodeficiency virus type-1 (HIV-1) and other retroviruses, contains three structurally distinct domains, an N-terminal domain, the catalytic core and a C-terminal domain. To elucidate their spatial arrangement, we have solved the structure of a fragment of HIV-1 integrase comprising the N-terminal and catalytic core domains. This structure reveals a dimer interface between the N-terminal domains different from that observed for the isolated domain. It also complements the previously determined structure of the C-terminal two domains of HIV-1 integrase; superposition of the conserved catalytic core of the two structures results in a plausible full-length integrase dimer.
