PATENTABSTRACTS

5100794 AMYLOLYTIC ENZYMES PRODUCING MICROORGANISMS, CONSTRUCTED BY RECOMBINANT DNA TECHNOLOGY AND THEIR USE FOR PERMENTATION PROCESSES Alexander Strasser, Feodor B Martens, Jurge Dohmen, Cornelius P Hollenberg, Dusseldorf, Federal Republic Of Germany The cloning of Schwanniomyces glucoamytase and alpha-amylase genes is taught. The genes are expressed in recombinant host cells.

5100798 METHOD FOR THE EXTRACTION OF A VITAMIN-K-DEPENDENT CARBOXYLASE COMPLEX AND THE USE THEREOF Cornelis Vermeer, Berry A Soute, Maastricht, Netherlands assigned to Rijksuniversiteit Liraburg Method for the extraction and insolubilization of a vitamin-K-dependent carboxylase complex from biological material, for instance a bovine liver homogenate, which can be used for the conversion of, for example, precursors of the blood coagulation factors II, VII, X and especially IX prepared via recombinant DNA-technotogy, the insolubilized carboxylase complex, as well as the prepared biologically active blood coagulation factors to be used in pharmaceutical compositions.

A colony stimulating factor, CSF- 1, is a lymphokine useful in overcoming the immunosuppression induced by chemotherapy or resulting from other causes. CSF-I is obtained in usable amounts by recombinant methods, including cloning and expression of the murine and human DNA sequences encoding this protein.

Basic proteins are isolated from protein mixtures which contain such basic proteins and which are obtained by enzymatic clevage of pro-
