Parallel analysis of tri-molecular biosynthesis with cell identity and function in single cells. [PDF]

open access: yes, 2019
Cellular products derived from the activity of DNA, RNA, and protein synthesis collectively control cell identity and function. Yet there is little information on how these three biosynthesis activities are coordinated during transient and sparse ...

Diversity and biosynthetic potential of culturable microbes associated with toxic marine animals [PDF]

open access: yes, 2013
Tetrodotoxin (TTX) is a neurotoxin that has been reported from taxonomically diverse organisms across 14 different phyla. The biogenic origin of tetrodotoxin is still disputed, however, TTX biosynthesis by host-associated bacteria has been reported.

Biosynthesis of lignans. Part I . Biosynthesis of Arctiin (3) and Phillyrin (5) [PDF]

open access: yes, 1977
Lignans constitute a class of naturally occuring phenolic compounds, widely distributed in higher plants. They are formally composed of two phenylpropanoid units, stercospecifically joined at the /f-carbon atoms of their side chains. Their biosynthesis

De novo formation of an aggregation pheromone precursor by an isoprenyl diphosphate synthase-related terpene synthase in the harlequin bug. [PDF]

open access: yes, 2018
Insects use a diverse array of specialized terpene metabolites as pheromones in intraspecific interactions. In contrast to plants and microbes, which employ enzymes called terpene synthases (TPSs) to synthesize terpene metabolites, limited information ...
