Novel PET Plastic Degrading Enzyme

Prof. Adam Godzik and colleagues from the University of California, Riverside have developed an enzyme with the potential of high PET degrading ability. Based on computer modeling experiments, this enzyme has the potential of high PET degrading ability. This enzyme may be useful because it may have higher PET degrading activity than existing enzymes and could provide a less expensive and more efficient means of recycling PET plastic.

(SD2020-014) Biosynthetic Production Of L-4-Chlorokynurenine

The non‐proteinogenic amino acid l‐4‐chlorokynurenine (l‐4‐Cl‐Kyn) is a next‐generation, fast‐acting oral prodrug for the treatment of major depressive disorder. Additional studies report that this drug candidate is effective in animal models for the treatment of neuropathic pain, epilepsy, and Huntington's disease.  After active transport across the blood–brain barrier, it is enzymatically converted into the active agent 7‐chlorokynurenic acid, which is a highly selective competitive antagonist of the N‐methyl‐d‐aspartic acid (NMDA) receptor.   Suicide is 2-7x higher in Veterans than non-veterans, and may be related to brain kynurenine pathway (KP) dysregulation and NMDA receptor (NMDAR) hyperactivation.  L-4-Chlorokynurenine (L-4-Cl-Kyn) is a neuropharmaceutical drug candidate that is in development for the treatment of major depressive disorder (Double-Blind, Placebo-Controlled, Phase 2 Trial to Test Efficacy and Safety of AV-101 (L-4-chlorokynurenine) as Adjunct to Current Antidepressant Therapy in Patients With Major Depressive Disorder (the ELEVATE Study)).

Method For Production Of Fatty Acids In Blue-Green Algae

Currently, renewable fatty acids are obtained solely from plant oils. Medium chain fatty acids (C8-C14) are typically sourced from coconut and palm oil, whereas longer chain saturated and unsaturated fatty acids are typically sourced from tallow, soy, corn or sunflower oil. Fatty acids are widely used for food, personal care products, industrial applications (e.g., lubricants, adhesives, detergents and plastics), as well as increasingly as biofuels. The demand for renewable fatty acids is rising and expanding. Given the current understanding of biological pathways it becomes possible to utilize other organisms, especially microorganisms, for the production of renewable chemicals such as fatty acids.

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.

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.
