Tetrapyrrole Signaling in Plants
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 ...

Response of Hemolytic and Photosynthetic Activity of Chattonella marina Complex Under Variable N:P Stoichiometry [PDF]
Chattonella marina is an ichthyotoxic, bloom-forming raphidophyte known for its hemolytic activity. However, the mechanisms by which nitrogen (N) and phosphorus (P) limitation influence this hemolytic toxicity remain poorly understood.

Peptide-Tetrapyrrole Supramolecular Self-Assemblies: State of the Art
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,

(5-n-Butyl-10,20-diisobutylporphyrinato)nickel(II)
The asymmetric unit of the title compound, [Ni(C32H36N4)], contains two independent molecules exhibiting an overall ruffled conformation of the porphyrin macrocycle and differing mainly in the positions of the methyl groups. The average Ni—N bond lengths
