Programmed Cell DEATH8 Interacts With Tetrapyrrole Biosynthesis Enzymes and ClpC1 to Maintain Homeostasis of Tetrapyrrole Metabolites in Arabidopsis

New Phytologist, 2023
Tetrapyrrole biosynthesis is a dynamically and strictly regulated process. Disruptions in tetrapyrrole metabolism influence many aspects of plant physiology, including photosynthesis, programmed cell death (PCD) and retrograde signaling, thus affecting ...

Insertion of cobalt into tetrapyrroles

2022
Vitamin B12 is one of the most complex cofactors known, and this chapter will discuss current understanding with regards to the cobalt insertion step of its syntheses. Two total syntheses of vitamin B12 were reported in the 1970s, which remain two of the most exceptional achievements of natural product synthesis.
