Method For Indefinite Storage And Preservation Of Membrane Precursors

UCLA researchers in the Department of Bioengineering have developed a novel strategy for the creation of biomimetic lipid bilayer membrane using a high freezing point lipid-containing solvent.  Using this method, the membrane precursor is frozen/immobilized prior to the completion of the spontaneous process of bilayer self-assembly, and the process can be resumed later by simply thawing and allowing membrane formation to resume.

Engineering Polyketide Synthase Machinery in Cyanobacteria

Complex polyketides include a family of natural products that possess a wide variety of pharmacological or biological activities. Numerous polyketides and their semisynthetic derivatives have been approved for clinical use in humans or animals, including antibiotics, antifungal agents, immunosuppressants, antiparasitic agents and insecticides. All these natural products share a common mechanism of biosynthesis and are produced by a class of enzymes called polyketide synthases (PKSs). Besides their essential role in the biosynthesis of a vast diversity of natural products, the versatility of PKSs can be further emphasized as they can be redesigned and repurposed to produce novel molecules that could be used as fuels, industrial chemicals, and monomers. Most polyketide producers are slow-growing, recalcitrant to genetic manipulation, or even non-culturable.

Synthetic Algal Promoters as a Tool for Increasing Nuclear Gene Expression in Green Algae

Algae have enormous potential as bio-factories for the efficient production of a wide array of high-value products, and eventually as a source of renewable biofuels. However, tools for engineering the nuclear genomes of algae remain scarce and limited in functionality, in part due to lack of strong promoters.

This simple approach uses genetically-modified soil bacterium to synthesize valuable hydrocarbons using recycled components. This novel process is environmentally-friendly and is more cost- and energy-efficient than current industrial synthesis.

Mammalian Cell Culture Optimization

Biotherapeutic proteins manufactured in cell culture systems have transformed modern medicine. Selling many tens of billions per year, new biotherapeutics such as monoclonal antibodies have delivered dramatic clinical results, while posing significant manufacturing problems.: During the cell culture manufacturing process, toxic bioproducts such as lactate and ammonia have posed considerable challenges in bioprocessing, since they limit cell growth and impact critical quality attributes of recombinant protein production (e.g., therapeutic drugs, enzymes). That is because the lactate alters the regulation of biosynthetic enzymes, and can lead to changes in pH in the culture. To mitigate the negative effects of lactic acid accumulation and control the culture pH, chemical ‘base’ is added to the media during the course of a bioprocess. However, the base addition negatively impacts the bioprocess by inhibiting growth and shortening the length of time in which the cells can produce the recombinant protein. This leads to reduced yield, and increased cost-of-goods. Thus, it is of great interest to eliminate lactate production, and UC San Diego researchers have recently developed a new process for achieving this.

The ubiquity of genes encoding GGDEF proteins in bacterial genomes has established the dominance of cdiG signaling in bacteria. A subfamily of GGDEF enzymes synthesizes the asymmetric signaling molecule cyclic AMP-GMP. Hybrid CDN-producing and promiscuous substrate-binding (Hypr) GGDEF enzymes are widely distributed and found in other deltaproteobacteria and have roles that include regulation of cAG signaling.  GGDEF enzymes that produce cyclic dinucleotides are especially of interest.    UC Berkeley researcher have developed a new method of preparing and using cyclic dinucleotides (CDNs) by contacting a CDN producing-enzyme (e.g., a GGDEF enzyme) with a precursor of a CDN under conditions sufficient to convert the precursor into a CDN. This method produces a variety of non-naturally occurring, asymmetric and symmetric CDNs and can be performed in vitro or in a genetically modified host cell. Also provided are CDN compositions that find use in a variety of applications such as modulating an immune response in an individual.
