NOVEL BIOLOGICAL EFFECT OF PLANT PEPTIDE HORMONE PHYTOSULFOKINE-α (PSK-α) AND ITS SELECTED ANALOGUES

摘要

Continuing our studies on phytosulfokine-α(H-Tyr(SO3H)-Ile-Tyr(SO3H)-Thr-Gln-OH) (PSK-α)(I), a sulfated plant growth factor , its C-terminal truncated tetrapeptide PSK-β(H-Tyr(SO3H)-Ile-Tyr(SO3H)-Thr-OH) (II), and its analogues, we performed a further search for its biological properties in respect to plant and animals.
