Tentoxin from Alternaria tenuis
Tentoxin from Alternaria tenuis (CAS: 28540-82-1), with the molecular formula C22H30N4O4 and a molecular weight of 414.50, is a naturally occurring phytotoxic cyclic tetrapeptide. It is known to induce chlorosis in dicotyledonous plant seedlings. Tentoxin is believed to act as an energy transfer inhibitor, potentially targeting the F1 moiety of photosynthetic H+-ATPases and interfering with cyclic photophosphorylation by inhibiting ATP synthesis.
Phytotoxicity Research
Tentoxin is utilized in studies investigating plant physiology and the mechanisms of phytotoxicity. Its ability to induce chlorosis in various dicotyledonous plants makes it a valuable tool for understanding plant stress responses.
Biochemical Studies of ATP Synthesis
This compound serves as a research agent in biochemical investigations focusing on ATP synthesis pathways. Tentoxin's postulated role as an energy transfer inhibitor at the F1 moiety of H+-ATPases allows for detailed kinetic and mechanistic studies of these crucial enzymes.
Cell Signaling and Neuroscience Research
As indicated by its category, Tentoxin may be employed in research exploring cell signaling pathways and neurological processes, though specific applications in these fields require further investigation.

| Application | Tentoxin is a naturally occurring phytotoxic cyclic tetrapeptide that is excreted by the fungi Alternaria alternata and Alternaria tenuis. It induces chlorosis in germinating seedlings of many dicotyledonous plants. Tentoxin has been postulated to inhibit cyclic photophosphorylation by acting as an energy transfer inhibitor at the terminal steps of ATP synthesis and to target the F1 moiety of photosynthetic H+-ATPases. A kinetic analysis of the action of tentoxin on the chloroplast F1 H+-ATPase (CF1) portion of chloroplast ATP synthase has been reported. |
