Heterologous Expression of Histidine Acid Phytase from Pantoea sp. 3.5.1 in Yarrowia lipolytica

Abstract

© 2018, Springer Science+Business Media, LLC, part of Springer Nature. The dimorphic yeasts Yarrowia lipolytica are used as effective expression system and are characterized by a high level of production of heterologous protein. In this work, we aimed to clone and express Pantoea sp. 3.5.1 agpP phytase gene in Yarrowia lipolytica. Genetic constructs containing the native phytase gene (agpP) under the control of the strong hybrid promoter hp4d and the signal peptide of the alkaline extracellular protease XPR2 gene, as well as the optimized gene (agpP-opt) of phytase under the control of two signal peptides—bacterial and yeast were obtained. Recombinant Y. lipolytica strains with integrated bacterial phytase genes were obtained and expression of phytase was analyzed.
