Partial purification and characterization of a trypsin-like proteinase from rabbit preimplantation uterine fluid.
Previous investigations have proved that proteinases are involved in implantation of the rabbit embryo into the uterine tissues. This study describes a trypsin-like enzyme found in the blastocyst fluid and uterine flushings at the time of implantation. The proteinase isolated from uterine flushings has a molecular mass of about 50 kDa and exists in two differently charged forms of pI 4.0 and 4....
متن کاملIsolation and Characterization of Trypsin Inhibitors (Kunitz Soybean Trypsin Inhibitor, Bowman-birk Inhibitor) in Soybean
Soybean (Glycine max (L.) Merr.) has emerged as one of the most economical and nutritious foods. Kunitz Soybean Trypsin Inhibitor (KSTI) and Bowman -Birk Inhibitor (BBI) are the two major trypsin inhibitors in soybeans. The ingested soybean trypsin inhibitors cause growth depression as demonstrated in different animal species and human. The main part of the present study was devoted to isolatio...
متن کاملEffect of oestrogen and progesterone on physical properties of rabbit oviduct fluid.
Since oviduct fluid acts as a medium for spermatozoa and ova during fertilization and early cleavage, this investigation was undertaken to determine any changes that occur in specific gravity, viscosity, osmolarity or dry matter content of rabbit oviduct fluid as the hormonal state changes from oestrogen to progesterone domination after fertilization. Five New Zealand white rabbits (4\m=.\5to 5...
متن کاملCompetition among trypsin inhibitors.
The experiments presented in this paper were designed to elucidate the kinetics of action of three protein inhibitors (from pancreas, soy bean, and egg white) on trypsin, and to discover how the inhibition by these substances was related to the action of diisopropyl fluorophosphate (DFP), mercuric chloride, and calcium salts on trypsin. The most, detailed work on the protein inhibitors of tryps...
متن کاملSignificance of Soya Trypsin Inhibitors
Although recent evidence clearly indicates that trypsin inhibitors (TO and low protein digestibility are the major factors responsible for the pancreatic hypertrophic and growth inhibitory effects of raw soybeans, there was uncertainty regarding the biological threshold level of TI at which these biological effects occur. To obtain such data, dehulled defatted flakes (10% dietary protein) conta...
