Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

617
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Protein Complexes with Interchangeable Parts

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

C4 Pathway and CAM

48.6K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The Calvin Benson Cycle

5.8K
Ribulose 1,5- bisphosphate carboxylase/oxygenase (RuBisCo) is a critical enzyme that catalyzes carbon dioxide assimilation during photosynthesis. However, it is an inefficient enzyme, having an extremely slow catalytic rate. A typical enzyme can process about a thousand molecules per second; however, RuBisCo fixes only around three-carbon dioxides per second. Photosynthetic cells compensate for this slow rate by synthesizing very high amounts of RuBisCo, making it the most abundant single...

Area of Science:

  • Synthetic biology
  • Plant science
  • Biochemistry

Background:

  • Enhancing C3 crop photosynthesis via carbon-concentrating mechanisms (CCMs) is crucial for increasing yields.
  • Previous attempts to engineer CCMs using algal pyrenoids or cyanobacterial carboxysomes faced challenges due to complex genetic requirements and protein specificity.

Purpose of the Study:

  • To develop a streamlined, modular synthetic system for creating functional carboxysome mimics in plants.
  • To establish a foundation for engineering improved photosynthetic efficiency in crops.

Main Methods:

  • Utilized encapsulin nanocompartments (QtEnc) from Quasibacillus thermotolerans as a chassis for synthetic carboxysomes.
  • Engineered a cargo-loading peptide to facilitate targeted encapsulation of diverse Rubisco isoforms within QtEnc.
  • Assessed the CO2-fixing activity of encapsulated Rubisco.

Main Results:

  • Successfully demonstrated targeted encapsulation of various Rubisco isoforms within QtEnc nanocompartments.
  • Confirmed that encapsulated Rubisco retained significant CO2-fixing activity.
  • Developed an isoform-agnostic system for creating synthetic carboxysome mimics.

Conclusions:

  • The developed synthetic encapsulin system provides a simpler and more tractable approach for engineering CCMs in plants compared to native structures.
  • This modular system lays the groundwork for future integration of carbonic anhydrase and further optimization of synthetic CCMs in crops.
