Patent number: 8268581Abstract: Compositions and methods are provided that are useful for predicting and controlling the stability of expressed polypeptides. The compositions and methods may be used to predict and as desired, increase or decrease the stability of proteins recombinantly expressed in mycobacteria, for example DesA3 expressed in Mycobacterium smegmatis. At the C terminus and the penultimate position, substitution to residues with charged side chains, large non-polar side chains, or no side chains can be used to reduce or inhibit the protein degradation. At the antepenultimate position from the C terminus, residues with no side chain or acidic side chains can increase the stability, i.e. reduce or inhibit the protein degradation. The combinational substitution of only the last three residues of polypeptides can make the polypeptides more stable during heterologous expression in mycobacterial hosts.Type: GrantFiled: April 28, 2009Date of Patent: September 18, 2012Assignee: Wisconsin Alumni Research FoundationInventors: Brian G. Fox, Yong Chang, Gary A. Wesenberg, Craig A. Bingman

Patent number: 7531317Abstract: The invention discloses a method of determining protease activity, in real time, using fluorescence polarization technology. In particular, the invention provides vectors and a method for their use, which expresses uncharacterized proteins conjugated to a fluorescence tag, which binds specifically to a fluorescent ligand. Cleavage of the recombinant protein results in a fragment of the expressed peptide and results in a change in fluorescence polarization of the fluorophore. The rate of change in fluorescence polarization can be measured in real time and is equivalent to the rate of protease cleavage.Type: GrantFiled: November 24, 2004Date of Patent: May 12, 2009Assignee: Wisconsin Alumni Research FoundationInventors: Brian G. Fox, Paul G. Blommel

Patent number: 5441887Abstract: A method is disclosed for degradation of a halogenated hydrocarbon compound such as trichloroethylene (TCE) which utilizes a soluble methane monooxygenase or a bacterium comprising the monooxygenase. Methylosinus trichosporium OB3b is a soluble methane monooxygenase-producing bacterium which when cultivated by continuous culturing comprising exposing the bacterium to a continuous-flow gas mixture of air and methane in a ratio of about 25:1-1:20, respectively. Methylosinus trichosporium OB3b is capable of degrading TCE at rates from about 500-10,000 micromoles per hour per gram cells.

Patent number: 5190870Abstract: A purified hydroxylase component of the soluble methane monooxygenase enzyme present in the bacterium Methylosinus trichosporium OB3b is found capable of oxidizing hydrocarbons under aerobic conditions in the presence of suitable reducing agents. The hydroxylase can be reduced by commercial reducing agents, such as sodium dithionite and photo- and electrochemical means when in the presence of electron transport components, such as methyl viologen and proflavin. The hydroxylase component can be obtained with high final specific activity when ferrous iron compounds and cysteine are included in the purification buffers used to extract the hydroxylase from bacterial cells.Type: GrantFiled: October 8, 1990Date of Patent: March 2, 1993Assignee: Amoco CorporationInventors: John D.
