Solution fold of HIV-1 Virus protein U cytoplasmic domain in the presence of DPC micelles

The structure was published by Wittlich, M., Koenig, B.W., Stoldt, M., Schmidt, H., and Willbold, D., in 2009 in a paper entitled "NMR structural characterization of HIV-1 virus protein U cytoplasmic domain in the presence of dodecylphosphatidylcholine micelles" (abstract).

The structure was determined using NMR spectroscopy and deposited in 2008.

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

The PDB entry contains the structure of Protein Vpu. This molecule has the UniProt identifier P19554 (VPU_HV1S1)search. The sample contained 45 residues which is < 90% of the natural sequence. Out of 45 residues 45 were observed and are deposited in the PDB.

The molecule is most likely monomeric.
