Title: The preparation of polypeptides having an amide carboxyl terminal end
Inventor: ENGELS JOACHIM
IPC: C12P21/02
Filed: 1984-07-26
Abstract: Polypeptides with a carboxamide carboxyl terminus and a methionine residue, which is optionally bound to a bacterial protein, at the amino end can be prepared by genetic engineering synthesis of the corresponding polypeptide with a glycine residue at the C terminus and the enzymatic conversion thereof into the amino group of the required carboxamide moiety. Peptides which have the amino-acid sequence of growth hormone releasing factor, part sequences thereof or modifications of these peptides can easily be obtained in this way. The genetic engineering synthesis is expediently carried out using two gene fragments which are chemically synthesised from single-stranded smaller fragments. The two gene fragments are then linked enzymatically to give the complete gene, incorporated in a suitable vector, amplified there, the peptide is isolated directly or as fusion protein and is converted enzymatically into the required amide.

Filed: 1987-06-19
Granted: 1990-06-06
Abstract: The surface of rolled material is descaled by contact with compressed abrasive powder. A working lever has on its curved surface contacting the powder a row of rectangular steps. The pitch of the steps corresponds to the average particle size of the abrasive powder. - The working element (1) is fitted to a lever (5), mounted on a shaft (8) with its hub (10). The surface which contacts the abrasive powder (4) is stepped (6) with parallel elements (17) at right angles to each other. The distance (a) should equal the average size of the particles of abrasive powder. The shaft (8) has a drive to create the force required to compress the powder and to remove the scale (3). The magnetic core (11) of an electromagnet (not shown) is applied to the working element (1) on the side opposite to the steps (7). The abrasive powder is magnetized by the electromagnet and loses its free-running capacity.
