Transport of bovine chymotrypsinogen into rabbit pancreatic cells.
LIEBOW, C., AND S. S. ROTHMAN. Transport of bovine chymotrypsinogen into rabbit pancreatic cells. Am. J. Physiol. 226(5) : 1077-1081. 1974.-Chymotrypsinogen uptake was measured into slices of rabbit pancreas incubated in bovine chymotrypsinogen-3H and albumin J311. Chymotrypsinogen uptake was 16 times greater than that for albumin. Chymotrypsinogen-3H was not readily “chased” by washing in cold...
متن کاملDetermination of Certain Amino Acids in Chymotrypsinogen, and Its Molecular Weight
1. A preparation of chymotrypsinogen, obtained from Dr. M. Kunitz, was analyzed for sulfur, the sulfur amino acids, tyrosine, and tryptophane. 2. The protein sulfur of chymotrypsinogen was accounted for as methionine, cysteine, and cystine. 3. A method is presented for calculating the minimum molecular weight of a protein from the distribution of the sulfur amino acids. In the case of chymotryp...
متن کاملThe Reversible Heat Denaturation of Chymotrypsinogen
Within a restricted range of pH and protein concentration crystalline chymotrypsinogen undergoes thermal denaturation which is wholly reversed upon cooling. At a given temperature an equilibrium exists between native and reversibly denatured protein. Within the pH range 2 to 3 the amount of denatured protein is a function of the third power of the hydrogen ion activity. The presence of small am...
متن کاملIonic interactions between bovine chymotrypsinogen A and chondroitin sulfate A.B.C.. A possible model for molecular aggregation in zymogen granules
The formation of large aggregates by ionic interactions between acidic glucosaminoglycans and cationic secretory proteins has been proposed as one of the critical steps in the concentration process in the condensing vacuoles of secretory cells. In this paper, this hypothesis was tested by studies on the interactions between bovine chymotrypsinogen A and chondroitin sulfate as a simplified model...
