文摘In the presence of a series of small organic molecules including 1, 4 dioxane, DMF, isopropanol, rDNA human insulin, mutants A21 Asn→Ser and (A21 Asn→Ser, B27 Thr→Arg) human insulin have been crystallized in both Zn 2+ containing and Zn 2+ free system. Preliminary crystallographic analyses show that they all belong to T 3R 3 structural type. The results indicate that, except phenolic derivatives and lyotropic anions reported before, some other appropriate organic molecules can also induce the T 3R 3 conformation transition of insulin.
