In addition, another larger molecular mass chymotrypsin activity was observed in activity blots that may correspond to the larger molecular mass caseinolytic and gelatinase activities. There was no difference in solubility of the zona by a-chymotrypsin among hamster oocytes matured in vitro and in vivo and 1-cell embryos. We conclude that a-chymotrypsin solubility cannot be used to detect premature zona reactions in the hamster. In some cases, it was necessary to pipette eggs through a small-bore pipette to remove the zonae after chymotrypsin treatment. The structure of the transition state for folding of chymotrypsin inhibitor 2 analyzed by protein engineering methods : evidence for a nucleation-condensation mechanism for protein folding. These authors removed zonae using chymotrypsin prior to fertilisation. The inhibition of trypsin was affected by the presence of chymotrypsin and vice-versa. The inhibitor reacts with trypsin and chymotrypsin separately, and it appears to affect the esterolytic activity of both enzymes similarly. Further, there were significant differences in the midgut protease profile for each stage, except for chymotrypsin. However, the inhibition was also seen against elastase-like chymotrypsin, although not to the same extent as that observed for trypsin. The chymotrypsin activity was too low to demonstrate meaningful inhibition by aprotinin. One unit of trypsin and chymotrypsin inhibiting activity is defined as the amount of inhibitor which inactivates 1 unit of the enzyme. The activity blot analyses indicated that at least some of these activities contributed to the hydrolysis of trypsin and chymotrypsin substrates. This activity was not observed in the chymotrypsin activity blots and is probably a different type of proteinase. In particular, soybean trypsin and trypsin/chymotrypsin inhibitors were most effective in reducing the in vitro caseinolytic activity of gut extracts. Folding of circular and permuted chymotrypsin inhibitor 2 : retention of the folding nucleus. |
