Indigo can be synthesized by microbial …

In nanobiotechnology, inorganic nanomaterials of a defined size and shape are synthesized by combining a compartment with precursor metal salts. Targeted mineralization is initiated by either directing precursor ions to the interior of a nanostructure via charge complementarity followed by the addition of a reducing agent, or by using genetic fusions of metal-binding/precipitating proteins and peptides.

This review showcases various coupling reagents which have been implemented specifically for large-scale amide synthesis via the condensation of an acid and amine, while highlighting the benefits and drawbacks of each reagent on an industrial scale.

discovered the role of mRNA in protein synthesis.

In a first study, we were able to employ encapsulins for the size-constrained synthesis of antimicrobial silver nanoparticles (Figure 8).

In fact, the one major modification we made after the prototypes was to split the training into two stages — first, the one day Demo Day where everyone learns what they will be signing up for, then the actual Story Circles training of 10 one hour sessions. The Demo Day is the weeding out that makes sure the participants in the Story Circles are sufficiently motivated since they are signing up on their own, not being required to do it (we’ve learned you can’t force this stuff on people).

In contrast, the research scientists — as we’ve seen from that first prototype group — have plenty of experience in the real world. They have taken part in, or at least watched, major projects fail to have much impact because their results were so poorly communicated. By the time we start working with them they are aware of what it means for a project to have “lacked a clear narrative.” That’s what experience brings.

FINAL SYNTHESIS – the segment ends with the double shot of the core message — that the reef is DYING — spoken by both , then repeated by Dean Miller. Did they cue Dean to say that bit or did the editor just find it in the interview. I’d guess the former. Then they put the visual lid on the presentation with the final aerial shot pulling away from the reef.

Large-Scale Applications of Amide Coupling Reagents …

Using biogenic protein-based nanostructures like encapsulins as templates and catalysts for the production of inorganic nanomaterials has a number of inherent advantages: The size-range accessible via encapsulins stretches from the nano- (single isolated encapsulin) to meso-scale (higher order encapsulin assemblies) allowing the synthesis of many different nanomaterials displaying specific properties only accessible at these scales. The defined size and shape of encapsulin compartments allows for the size-constrained synthesis of inorganics in their interior, leading to a homogeneous and monodisperse population of nanosized objects. The possibility to use both the interior and exterior surfaces of shell-like nanostructures like encapsulins allows for the potential synthesis of nanomaterials that integrate multiple functionalities. And lastly, using biology for the synthesis of inorganics will decrease the amount of harmful chemicals and solvents used in inorganic syntheses as well as reduce the energy input needed.

This approach will prove useful in improving the yield of a number of important engineered pathways including the antimalarial drug artemisinin and medically-relevant alkaloids. Artemisinin biosynthesis is known to proceed via a toxic aldehyde intermediate which could be selectively confined inside protein compartments by targeting the respective pathway step to the inside of encapsulins. Likewise, the biosynthesis of many engineered alkaloids is thought to form reactive nitrogen-based heterocyclic intermediates. This problem could also be approached using engineered compartmentalization resulting in reduced host toxicity and thus higher yields.

Compared with plant ribulose-1,5-bisphosphate carboxylase/oxygenase (RuBisCO), the key CO2-fixing enzyme, cyanobacteria have evolved faster enzymes that are more sensitive to O2. What makes cyanobacteria nonetheless thrive in high oxygen environments is their sophisticated CCM. A core component of this CCM is a bacterial microcompartment called the carboxysome. RuBisCO and carbonic anhydrase (CA) are encapsulated inside these protein organelles leading to a high local concentration of CO2 around the RuBisCO active site. The selectively permeable protein shell of the carboxysome minimizes internal O2 concentrations thus preventing wasteful photorespiration.

Using encapsulins will allow for the simultaneous presentation of different metal-precipitating peptides on the compartment inside and outside based on capsid protein and TP fusions. This will enable us to generate new composite materials and nano-alloys in vivo and in vitro not found in nature that could be used as inorganic catalysts, electrodes, photovoltaic and magnetic materials and photonic nano-devices. Genetically encoding the synthesis of functional nanomaterials would allow advanced applications as non-invasive biological sensing and control systems. Using biology would also enable us to combinatorially integrate mutational screens of capsid proteins and metal-binding/precipitating peptides and media compositions resulting in the high-throughput synthesis of inorganics, an approach not feasible using classical inorganic chemistry due to the extremes in temperature and pressure involved. Another distinguishing feature compared to inorganic chemistry is the ability of biological systems to generate non-equilibrium structures and materials with unique properties. Using TPs, it would also be possible to specifically embed one or multiple enzymes inside an inorganic nanoparticle of defined size leading to porous organic-inorganic hybrid-materials.
