  • Title: Membrane relocation but not tight binding of human immunodeficiency virus type 1 Gag particles myristoylated in Escherichia coli.
    Author: Morikawa Y, Kinoshita A, Goto T, Tomoda H, Sano K.
    Journal: Virology; 2001 May 10; 283(2):343-52. PubMed ID: 11336559.
    Abstract:
    Expression of human immunodeficiency virus Gag protein and the N-terminal matrix (MA) domain in Escherichia coli yielded spherical structures in the cytoplasm. When human N-myristoyltransferase was coexpressed, both Gag and MA were fully myristoylated and spherical structures were relocated in close proximity to the cytoplasmic membrane. However, neither myristoylated Gag nor MA exhibited tight binding to E. coli membrane, suggesting that myristoylation in E. coli did not confer membrane affinity on Gag despite the relocation. Our data also suggest that the morphogenetic pathway of Gag particles in prokaryotic cells differs from that in eukaryotic cells despite biochemical similarities of in the form of Gag expressed.
