Tetrapyrrole Signaling in Plants
Frontiers in Plant Science, 2016 Tetrapyrroles make critical contributions to a number of important processes in diverse organisms. In plants, tetrapyrroles are essential for light signaling, the detoxification of reactive oxygen species, the assimilation of nitrate and sulfate ...

The Role of Tetrapyrrole- and GUN1-Dependent Signaling on Chloroplast Biogenesis
Plants, 2021 Chloroplast biogenesis requires the coordinated expression of the chloroplast and nuclear genomes, which is achieved by communication between the developing chloroplasts and the nucleus.

Peptide-Tetrapyrrole Supramolecular Self-Assemblies: State of the Art
Molecules, 2021 The covalent and noncovalent association of self-assembling peptides and tetrapyrroles was explored as a way to generate systems that mimic Nature’s functional supramolecular structures. Different types of peptides spontaneously assemble with porphyrins,

Tolyporphins–Exotic Tetrapyrrole Pigments in a Cyanobacterium—A Review
Molecules, 2023 Tolyporphins were discovered some 30 years ago as part of a global search for antineoplastic compounds from cyanobacteria. To date, the culture HT-58-2, comprised of a cyanobacterium–microbial consortium, is the sole known producer of tolyporphins ...

Philosophical Transactions of the Royal Society B: Biological Sciences, 2020 In plants, tetrapyrrole biosynthesis occurs in chloroplasts, the reactions being catalysed by stromal and membrane-bound enzymes. The tetrapyrrole moiety is a backbone for chlorophylls and cofactors such as sirohaems, haems and phytochromobilins.

The Retrograde Signaling Protein GUN1 Regulates Tetrapyrrole Biosynthesis
Proceedings of the National Academy of Sciences of the United States of America, 2019 Significance The signaling pathway between chloroplasts and the nucleus (retrograde signaling) is important for the correct development of the photosynthetic apparatus of plant seedlings.

Transcriptional regulation of tetrapyrrole biosynthesis in Arabidopsis thaliana
Frontiers in Plant Science, 2016 Biosynthesis of chlorophyll (Chl) involves many enzymatic reactions that share several first steps for biosynthesis of other tetrapyrroles such as heme, siroheme and phycobilins.
