The construction of cDNA library from calf pancreas allowed us to examine the mRNA levels of four pancreatic hydrolases (chymotrypsin, lipase, trypsin and amylase) during postnatal development in preruminant and ruminant animals. The lack of parallel variations in the levels of the enzyme specific activities suggested that protein synthesis was not(More)
A full-length cDNA clone encoding bovine pancreatic preprocarboxypeptidase A was isolated and sequenced. The 1405-base pair insert contains a 26-nucleotide 5'-noncoding region, a 1260-nucleotide open reading frame and a 76-nucleotide 3'-noncoding fragment plus a poly(A) tail of at least 43 nucleotides. The open reading frame encodes a protein of 419 amino(More)
