Fibroblast growth factor(FGF-1)lacks amino-terminal signal peptide, so it can't release through the classical endoplasmic reticulum(ER)-Golgi pathway.

A synthetic method for substituted amino-terminal group polyester hyperdispersants is researched and the optimum conditions for polyester chain with suitable length are chosen.

Results the three dimensional structure of sed, similar to that of other enterotoxin superantigens, was composed of two domains: amino terminal domain and carboxyl terminal domain.
