Function of Tetrapyrroles, Regulation of Tetrapyrrole Metabolism and Methods for Analyses of Tetrapyrroles [PDF]
AbstractTetrapyrroles are essential cofactors and pigments. Photosynthetic organisms share the use of the highest diversity of tetrapyrrole end products. This report intends to call readers’ attention to the recent achievements in research on tetrapyrrole biosynthesis and the current hot topics in tetrapyrrole biosynthesis, including posttranslational ...

Thiol-based redox control of enzymes involved in the tetrapyrrole biosynthesis pathway [PDF]
The last decades of research brought substantial insights into tetrapyrrole biosynthetic pathway in photosynthetic organisms. Almost all genes have been identified and roles of seemingly all essential proteins, leading to the synthesis of heme, siroheme,

PAPP5 is involved in the tetrapyrrole mediated plastid signalling during chloroplast development. [PDF]
The initiation of chloroplast development in the light is dependent on nuclear encoded components. The nuclear genes encoding key components in the photosynthetic machinery are regulated by signals originating in the plastids.

Towards triptycene functionalization and triptycene-linked porphyrin arrays
Herein, 9,10-diethynyltriptycene is investigated for its use as a rigid isolating unit in the synthesis of multichromophoric arrays. Sonogashira cross-coupling conditions are utilized to attach various porphyrins and boron dipyrromethenes (BODIPYs) to ...

An Easily Prepared Monomeric Cobalt(II) Tetrapyrrole Complex that Efficiently Promotes the 4e–/4H+ Peractivation of O2 to Water [PDF]
The selective 4e–/4H+ reduction of dioxygen to water is an important reaction that takes place at the cathode of fuel cells. Monomeric aromatic tetrapyrroles (such as porphyrins, phthalocyanines, and corroles) coordinated to Co(II) have been considered ...
