In Drosophila melanogaster, nutrition controls body size by acting through the Forkhead Box class O (FoxO)/Ultraspiracle complex to regulate nutrition-sensitive ecdysone biosynthesis, thereby controlling the switch to stop growth.

A new type of hybrid nonribosomal peptide synthetase (NRPS)-like-pteridine synthase biosynthetic pathway has been illuminated via genome mining.

Upon deletion of threonine deaminases, biosynthesis of isoleucine is rescued by two promiscuous reactions, one emerges under aerobic conditions and the other is naturally active under anaerobic conditions.

Analysis of suppressor mutants led to the identification of a novel signalling pathway that regulates peptidoglycan biosynthesis in Gram-positive bacteria.

The important role of serine biosynthesis in Müller cells may explain why the macula is so much more prone to developing disease than the rest of the retina.

The entire biosynthetic pathway for the diterpenoid forskolin in Coleus forskohlii has been reconstituted in yeast.

Insights into the basic metabolic architecture and adaptations of malaria parasites for growth within human erythrocytes exemplify how incisive knowledge of biochemical pathways and mechanisms may be leveraged to develop new therapies.

During cardiogenesis, the major role of glucose is not the catabolic extraction of energy but the anabolic biosynthesis of nucleotides.

The glucose-sensing transcription factor MondoA regulates zebrafish epiboly via cholesterol biosynthesis genes including the human disease gene Nsdhl, revealing an unknown role for metabolic glucose signalling in vertebrate development.

An ensemble of conserved G2-quadruplex structures in the untranslated regions of messenger RNAs from genes in the polyamine bioysynthesis pathway sense polyamine levels and regulate polyamine synthesis in cells.
