The Keto Functions of Heme d1 Are Introduced by NirF and NirC
ChemBioChem, Volume 27, Issue 10, 27 May 2026.During heme d1 biosynthesis, the proteins NirF and NirC together catalyze the formation of dihydro‐heme d1, thereby introducing the unique keto functions of heme d1. In this paper, the development of an in vitro enzyme activity assay for NirF/NirC is described, which demonstrates the function of the two proteins for the first time.

Advanced Science, Volume 13, Issue 29, 22 May 2026.PirN was identified as a previously uncharacterized PsbO‐interacting protein specifically induced in nitrate‐grown cyanobacteria. Loss of PirN leads to coordinated downregulation of PsbO and the nitrate reductase NarB, causing decreased PSII activity and impaired growth under nitrate conditions. Complementation with either PsbO or NarB largely restores

Advanced Science, Volume 13, Issue 25, 4 May 2026.In maize, the bHLH transcription factor ZmbHLH118 directly binds to the promoter of ZmCLCa and inhibits its expression. Tonoplast‐localized ZmCLCa mediates NO3− influx into the vacuole to regulate intracellular NO3− homeostasis, modulating nitrate uptake and metabolism, plant growth, and grain yield.
