Patent number: 6165787Abstract: Dimerization and oligomerization of proteins are general biological control mechanisms that contribute to the activation of cell membrane receptors, transcription factors, vesicle fusion proteins, and other classes of intra- and extracellular proteins. We have developed a general procedure for the regulated (inducible) dimerization or oligomerization of intracellular proteins. In principle, any two target proteins can be induced to associate by treating the cells or organisms that harbor them with cell permeable, synthetic ligands. To illustrate the practice of this invention, we have induced: (1) the intracellular aggregation of the cytoplasmic tail of the .zeta.Type: GrantFiled: May 29, 1998Date of Patent: December 26, 2000Assignees: Board of Trustees of Leland Stanford Jr. University, President and Fellows of Harvard CollegeInventors: Gerald R. Crabtree, Stuart L. Schreiber, David M. Spencer, Thomas J. Wandless, Peter Belshaw

Patent number: 6107063Abstract: The invention relates to processes for the microbial production of L-isoleucine. To this end, in a gene in vitro of a threonine dehydratse, one or more bases in the gene region coding the enzyme's allosteric domains are exchanged in such a way that at least one amino acid in the amino acid sequence of the allosteric domains of the enzyme is replaced by another so that the enzyme is no longer inhibited by L-isoleucine feedback. Furthermore, concrete amino acid exchanges in the amino acid sequence of the enzyme are effected in a gene in vitro of a threonin dehydratase of Corynebacterium glutamicum by base exchange both outside and inside and outside the gene region coding the allosteric domains of the enzyme si that, after the transformation of such mutated threonine dehydratase genes into a threonine or L-isoleucine-producing host cell, the latter repeatedly forms L-isoleucine.Type: GrantFiled: March 20, 1997Date of Patent: August 22, 2000Assignee: Forschungszentrum Juelich GmbHInventors: Bettina Moeckel, Lothar Eggeling, Hermann Sahm

Patent number: 6030784Abstract: An improved method for the simultaneous sequence-specific identification of mRNAs in a mRNA population allows the visualization of nearly every mRNA expressed by a tissue as a distinct band on a gel whose intensity corresponds roughly to the concentration of the mRNA. In general, the method comprises the formation of cDNA using anchor primers to fix a 3'-endpoint, producing cloned inserts from the cDNA in a vector containing a bacteriophage-specific promoter for subsequent RNA synthesis, generating linearized fragments of the cloned inserts, preparing cRNA, transcribing cDNA from the cRNA using a set of primers, and performing PCR using a 3'-primer whose sequence is derived from the vector and a set of 5'-primers that is derived from the primers used for transcription of cDNA from cRNA. The method can identify changes in expression of mRNA associated with the administration of drugs or with physiological or pathological conditions.Type: GrantFiled: March 5, 1998Date of Patent: February 29, 2000Assignee: The Scripps Research InstituteInventors: J. Gregor Sutcliffe, Mark G. Erlander
