Construction of a novel MK-4 biosynthetic pathway in Pichia pastoris through heterologous expression of HsUBIAD1.

In this study, we constructed a novel synthetic pathway in P. pastoris for the biosynthesis of the high value-added prenylated product MK-4 through heterologous expression of HsUBIAD1 and strengthened accumulation of GGPP. This approach could be further developed and accomplished for the biosynthesis of other prenylated products, which has great significance for theoretical research and industrial application.
