| Popis: | Sericin is the silk protein enveloping fibroin fibers in cocoons. Sericin hydrolysate protects cultured Sf9 insect cells from death caused by serum deprivation; the activity depends on the repeats of 38 amino acids. A partial peptide from the 38 residues, SGGSSTYGYS, inhibited serum-deprivation death as well. Cell viabilities in the presence of 10% (v/v) foetal calf serum, no additives and 1 mM: SGGSSTYGYS were 96, 12 and 31% on the third day after inoculation, respectively. Aromatic residues seemed to be important because SGGSSTWGWS had the same activity as SGGSSTYGYS but SGGSSTAGAS had no activity. |
