[Expression of hybrid genes containing sequences coding for human adrenocorticotropic hormone in Escherichia coli
Abstract:
E. coli strains producing a hybrid protein containing human adrenocorticotropic hormone (ACTH) and protein A of S. aureus were obtained. The sequence coding for ACTG was obtained from the bovine one using oligonucleotide-directed mutagenesis. The ACTG gene was linked with the protein A gene and its derivatives by synthetic adaptors. It was shown that each of the constructed plasmids directed the synthesis of hybrid protein in E. coli. This protein was purified on IgG-Sepharose. Then ACTH was obtained by HPLC after specific hydrolysis. The amino acid composition of purified sample was determined.

The Central Dogma
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...
