摘　　要：A proteinase responsible for degradation of yolk proteins has been discovered in oocyte of Antheraea pernyi which was found to found to hydrolyze vitelluin effectively in acidic pH. Using bovine hemoglobin as substrate,the optimum pH was determine3d at 3.5.Unaffected by EDTA and DipF, the activity of the proteinase was strongly inhibited by E64 and other thiol blocking reagents. It is thus very likely to be a cysteine proteinase. Activity of the proteinas. was found to be increasing in developing oocyte.

关 键 词：Antheraea pernyi Yolk proteins Degredative proteinase.
