Formate as an Inhibitor of Photosynthetic Electron Flow
Zeitschrift für Naturforschung C, 1984 The effects of formate on the Hill reaction in isolated broken pea chloroplasts were investigated. Addition of formate to chloroplasts has two distinct effects: I. basal electron flow can be stimulated 3-fold; 2. uncoupled electron flow is inhibited. The stimulating effect is due to uncoupling by formate and appears instantaneous.

The Ability of Cyanobacterial Cells to Restore UV-B Radiation Induced Damage to Photosystem II is Influenced by Photolyase Dependent DNA Repair [PDF]
, 2013 Damage of DNA and Photosystem-II are among the most significant effects of UV-B irradiation in photosynthetic organisms. Both damaged DNA and Photosystem-II can be repaired, which represent important defense mechanisms against detrimental UV-B effects ...

Phosphoenolpyruvate Carboxykinase Is Involved in the Decarboxylation of Aspartate in the Bundle Sheath of Maize [PDF]
, 1999 We recently showed that maize (Zea mays L.) leaves contain appreciable amounts of phosphoenolpyruvate carboxykinase (PEPCK; R.P. Walker, R.M. Acheson, L.I. Técsi, R.C. Leegood [1997] Aust J Plant Physiol 24: 459–468).

Picrate as an Inhibitor of Photosystem II in Photosynthetic Electron Transport [PDF]
European Journal of Biochemistry, 1982 2,4,6‐Trinitrophenol (picric acid) is an effective inhibitor of photosynthetic electron transport (pI50 value 6.82). By means of artificial donor and acceptor systems its site of inhibition was located at the reducing side of photo‐system II. In addition, picric acid also uncouples photophosphorylation but a much higher concentration is required than ...

Crystallographic studies of the Escherichia coli quinol-fumarate reductase with inhibitors bound to the quinol-binding site [PDF]
, 2002 The quinol-fumarate reductase (QFR) respiratory complex of Escherichia coli is a four-subunit integral-membrane complex that catalyzes the final step of anaerobic respiration when fumarate is the terminal electron acceptor.
