Chymotrypsinogen molecular weights

How long are the polypeptide chains in proteins As Table 3-2 shows, lengths vary considerably. Human cytochrome c has 104 amino acid residues linked in a single chain bovine chymotrypsinogen has 245 residues. At the extreme is titin, a constituent of vertebrate muscle, which has nearly 27,000 amino acid residues and a molecular weight of about 3,000,000. The vast majority of naturally occurring proteins are much smaller than this, containing fewer than 2,000 amino acid residues.

As in bovine chymotrypsinogens A and B, the single NH2-terniinal residue in porcine chymotrypsinogen A is half-cystine. The amino acid composition and the molecular weight of the protein are given in Table I. 

In the past, we have ascribed these differences in protein stabilization to Timasheff s thermodynamic mechanism. The only protein for which the needed thermodynamic parameters have been measured in the presence of all three cryo-protectants is chymotrypsinogen [83,84] Table 1. Although these data are not directly applicable to LDH, the general trends shown should be relevant to any protein. The increase in chymotrypsinogen chemical potential, (6 i2/Sm3), in the presence of either of two different molecular weights of PEG (e.g., = 400 or...
