Abstract:
Natural products have demonstrated value across numerous application areas, with antibiotics a notable historical example. Native cellular hosts provide an initial option in efforts to harness natural product production. However, various complexities associated with native hosts, including fastidious growth traits and limited molecular biology tools, have prompted an alternative approach termed heterologous biosynthesis that relies upon a surrogate biological system to reconstitute the biosynthetic sequence stemming from transplanted genetic blueprint. In turn, heterologous biosynthesis offers the benefit of enzymatically driven complex natural product formation combined with the prospect of improved compound access via scalable cellular production. In this review, we conduct a literature meta-analysis of heterologous natural product biosynthesis over the period of 2011-2020 with the goal of identifying trends in heterologous natural product host selection, target natural products, and compound-host selection tendencies, with associated commentary on the research directions of heterologous biosynthesis based upon this analysis.

RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
