Abstract

Polyhydroxyalkanoate (PHA) synthase, the key enzyme in polyester biosynthesis of bacteria, has been targeted to various organelles in yeasts and plants using respective signal peptides. Here, we report that the sequences derived from SNARE domains efficiently target and integrate the PHA synthase from Pseudomonas putida CA-3 to the membrane of secretory vesicles in Saccharomyces cerevisiae. The studies with the enhanced green fluorescent protein confirm the localization of synthase enzyme in the vesicles of S. cerevisiae.
