Informação sobre produto

• Nome: Phytosulfokine-α
• Sinónimos: Tyr(SO3H)-Ile-Try(SO3H)-Thr-Gln ammonium salt
• Marca: Biosynth
• Descrição: Phytosulfokine (PSK) was introduced in 1996 by Matsubayashi and Sakagami of Nagoya University. It is the world's first peptide phytohormone to be isolated from asparagus culture medium. Tyr undergoes post-translational sulfation modification, which is essential for bioactivity. As an example of oxidative peptides showing bioactivity, in animals, CCK-octapeptide (26-33) (sulfated form), PCK-4100-V, CCK-33 (Human), PCK-4201-S and CCK-33 (Porcine), PCK-4176-S are known, but they were first found in plants. The functions of phytosulfokine are i) plant cell proliferation and differentiation activity acting at nanomolar concentrations ii) chlorophyll synthesis-promoting activityiii) formation of adventitious roots and buds iv) adventitious embryogenesisv) involvement in disease resistance The active expression of these PSKs is accompanied by membrane-bound LRR receptors, which are PSK receptors. Leucine-rich repeat receptor-like kinase is involved.
