His-Trp cation-π interaction and its structural role in an α-helical dimer of HIV-1 Vpr protein.

Biophysical chemistry - 1 Jan 2000

Kamiyama Takayuki, Miura Takashi, Takeuchi Hideo

Abstract excerpt

Vpr is a multifunctional accessory protein of HIV-1 virus and was previously proposed to assume an antiparallel helical dimer with the third helices HIII of different subunits facing each other. In this study, we have examined the structure and stability of the antiparallel dimer by using a fragment peptide, Vpr52-80, spanning the HIII region. The present analyses of fluorescence, circular dichroism, and UV...
