abstract = {Viral accessory proteins of the human immunodeficiency
virus (HIV), including virus protein R (Vpr), are crucial
for the efficient replication of the virus in the host
organism. While functional data are available for HIV-1 Vpr,
there is a paucity of data describing the function and
structure of HIV-2 Vpr. In this report, the construction of
a His6-MBP-intein1-Vpr-intein2-Cyt b5-His6 fusion protein is
presented. Unlike previous research efforts where only
microgram quantities of HIV-1 Vpr could be produced, this
construct enabled soluble milligram yields via an
Escherichia coli over-expression system. Straightforward
protein purification of HIV-2 Vpr was achieved by standard
chromatography routines and autocatalytic intein cleavage.
Preliminary structural studies by circular dichroism (CD)
and NMR spectroscopy revealed that the protein is stable in
the presence of micellar concentrations of the detergent DPC
and adopts an α-helix secondary structure.},
