Analysis of the structure and subcellular location of filamentous phage pIV.

Abstract excerpt

The gene IV protein of filamentous bacteriophages is an integral membrane protein required for phage assembly and export. A series of gene IV::phoA fusion, gene IV deletion, and gene IV missense mutations have been isolated and characterized. The alkaline phosphatase activity of the fusion proteins suggests that pIV lacks a cytoplasmic domain. Cell fractionation studies indicate that the carboxy-terminal half of...
