Abstact

The structure of the C-terminal DNA-binding domain of human immunovirus-1 integrase has been refined using nuclear magnetic resonance spectroscopy. The protein is a dimer in solution and shows a well-defined dimer interface. The folding topology of the monomer consists of a five-stranded beta-barrel that resembles that of Src homology 3 domains. Compared with our previously reported structure, the structure is now defined far better. The final 42 structures display a back-bone root mean square deviation versus the average of 0.46 A. Correlation of the structure with recent mutagenesis studies suggests two possible models for DNA binding. Proteins 1999;36:556-564.
