However, amphioxus ubf80 also showed some unique characters such as its amino acid residues at sites 39, 54, 63 and 74 in the cep. it appears that amphioxus not only represents an organism tr ansitional from invertebrates to vertebrates in phylogeny but also a possible diverged form radiated from the chordate ancestor at early chordate evolution. the possibility that some mutations in ub genes have taken place in different lines early at the divergence of plants and animals is also discussed

  19. Whole mount in situ hybridization showed that amphihmgb transcripts were present ubiquitously in the early embryos from zygote to neurula, but they decreased gradually in mesoderm and endoderm and neural tube with development, and became restricted to epidermal cells in the hatched larva. it appear s that hmgb plays a role in the mitosis and differentiation of embryonic cells. another amphioxus cdna, amphiubf80, encoding ubiquitin / ribosomal fused protein s27a, was isolated from the gut cdna library of b. belcheri tsingtauense

    S004cdna序列編碼一個156個氨基酸殘基組成的蛋白質，與人的泛素蛋白ubf80具有較高的氨基酸序列同源性（ 145 / 156同源） ，且該蛋白具有泛素蛋白ubf80所共有的兩個結構域，即由72個氨基酸組成的泛素介導的蛋白降解結構域和由48個氨基酸組成的核糖體蛋白s27a結構域。
  20. The hemagglutinating activity of amphioxus skin mucus was decreased after heating at 60 for 30 min, and was almost lost upon heating at 100 for 30 min. the hemagglutinating activity of the skin mucus remained stable in the ph range from 6 to 10, but it was inactivated at ph above 10 or below 6. the hemagglutinating activity in the skin mucus is inhibited by d - galactose, which is same with the hemagglut inating activity of the humoral fluids of amphioxus

    在60保溫30分鐘后，凝集素的凝集活性下降，在100保溫30分鐘后，凝集素凝集活性幾乎完全消失；在ph6 - 10的范圍內，凝集素的凝集活性穩定， ph大於10小於6的條件下，凝集素的凝集活性消失；文昌魚體表粘液中的凝集素受d -半乳糖苷的抑制。
