Solution structure of the HIV-1 nucleocapsid (NCp7(12-55)) complexed with the DNA (-) Primer Binding Site

The structure was published by Bourbigot, S., Ramalanjaona, N., Boudier, C., et al., Mely, Y., Bouaziz, S., and Morellet, N., in 2008 in a paper entitled "How the HIV-1 nucleocapsid protein binds and destabilises the (-)primer binding site during reverse transcription." (abstract).

The structure was determined using NMR spectroscopy and deposited in 2005.

The experimental data on which the structure is based was also deposited.

This PDB entry contains a complex of 2 biomacromolecules, namely 5'-D(*GP*TP*CP*CP*CP*TP*GP*TP*TP*CP*GP*GP*GP*C)-3' and Nucleocapsid protein* (NC*).

It also contains one or more heterogenic compounds (e.g., ligands, co-factors, ions, modified amino acids, etc.); see here for a complete list.

The molecule most likely forms heterodimers.
