Cloning and expression of the external-glycoprotein gene mutant from HIV-2 in the methylotrophic yeast Pichia pastoris and identification of the glycoprotein.

Abstract excerpt

To achieve high-level expression of HIV-2(ROD) external glycoprotein gp105 in Pichia pastoris, the gp105 gene mutant tP1, with the 5' non-functional region of the gp105 gene removed, was obtained by PCR amplification and was cloned into secreted expression vector pHILS1. The His(+)Mut(s) recombinant P. pastoris strain was screened by PCR and induced by methanol. SDS/PAGE and Western-blot analyses showed that...
