Article Abstract
Terpenoids, or isoprenoids, are a family of compounds with great structural diversity which are essential for all living organisms. In cyanobacteria, they are synthesized from the methylerythritol-phosphate (MEP) pathway, using glyceraldehyde 3-phosphate and pyruvate produced by photosynthesis as substrates. The products of the MEP pathway are the isomeric five-carbon compounds isopentenyl diphosphate and dimethylallyl diphosphate, which in turn form the basic building blocks for formation of all terpenoids. Many terpenoid compounds have useful properties and are of interest in the fields of pharmaceuticals and nutrition, and even potentially as future biofuels. The MEP pathway, its function and regulation, and the subsequent formation of terpenoids have not been fully elucidated in cyanobacteria, despite its relevance for biotechnological applications. In this review, we summarize the present knowledge about cyanobacterial terpenoid biosynthesis, both regarding the native metabolism and regarding metabolic engineering of cyanobacteria for heterologous production of non-native terpenoids.

Tetrahydro-β-carboline 1 (MMV008138) controls growth of asexual blood-stage by inhibiting IspD, an enzyme in the MEP pathway for synthesis of a critical metabolite, isopentenyl pyrophosphate (IPP). We have previously investigated the structure activity relationship (SAR) of three of its four rings (B, C, and D). In this report we investigate the SAR of the benzo- ( A-ring) of 1, with the goal of increasing its antimalarial potency and metabolic stability.

Pelargonium graveolens, valued for its essential oil, is significantly influenced by its endosymbiotic associations impacting its physiology and phytochemistry, though the exact mechanisms driving this modulation remain largely unexplored. This study unveils that inoculating Pseudomonas oryzihabitans CB24 into P. graveolens significantly alters plant's lipid dynamics, leading to increased accumulation of chloroplast glycerolipids like monogalactosyldiacylglycerol (MGDG) and sulfolipids, sulfoquinovosyldiacylglycerol (SQDG).

Gram-negative bacteria are increasingly resistant to antibiotics, making the development of effective antimicrobial agents crucial in combating global health threats. In this context, IspH, a key enzyme in the methylerythritol phosphate (MEP) pathway essential for isoprenoid biosynthesis, represents a promising target to develop antibacterial agents for ablating Gram-negative bacteria. However, the anionic groups commonly present in IspH inhibitors hinder their ability to penetrate bacterial cells, preventing them from exhibiting biological activity.

Terpenoids are structurally complex natural products with broad agricultural and therapeutic value, yet their low natural abundance and oxidative tailoring requirements complicate scalable production. Conventional microbial hosts often fail to support cytochrome P450-mediated oxidative tailoring, limiting access to complex derivatives. Here, we developed two hosts as alternative chassis, leveraging their extensive biosynthetic capabilities and native oxidative enzyme repertoires.
