Synthetic Biology

5.8K
Synthetic biology is an interdisciplinary science that involves using principles from disciplines such as engineering, molecular biology, cell biology, and systems biology. It involves remodeling existing organisms from nature or constructing completely new synthetic organisms for applications such as protein or enzyme production, bioremediation, value-added macromolecule production, and the addition of desirable traits to crops, to name a few.

C4 Pathway and CAM

50.2K
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.

Amino Acid Biosynthetic Pathways01:29

Amino Acid Biosynthetic Pathways

1.6K
Amino acid biosynthesis is essential for cell growth, protein synthesis, and metabolic regulation. Cells generate essential and non-essential amino acids from metabolic intermediates to sustain vital biological functions. These intermediates originate from key metabolic pathways: glycolysis, the tricarboxylic acid (TCA) cycle, and the pentose phosphate pathway. Important precursors include α-ketoglutarate, pyruvate, oxaloacetate, phosphoenolpyruvate, and erythrose-4-phosphate, which...

Area of Science:

  • Computational biology
  • Systems biology
  • Bioinformatics

Background:

  • Biological pathways are crucial for cellular functions and are extensively studied using computational and cell biology approaches.
  • Existing tools facilitate the creation, validation, and visualization of biological pathway models using the BioPAX standard.
  • A significant gap exists in the availability of a generic software framework for simulating these BioPAX models.

Purpose of the Study:

  • To introduce a generic simulation framework specifically designed for BioPAX models.
  • To address the lack of a standardized simulation environment for biological pathway data.
  • To enhance the reproducibility and modularity of biological pathway modeling.

Main Methods:

  • Developed a generic simulation framework for BioPAX models.
  • Separated the execution model from the BioPAX model structure for improved modularity and reproducibility.
  • Utilized principles of discrete event systems and multi-agent systems.
  • Implemented automatic generation of hierarchical multi-agent systems from BioPAX models.

Main Results:

  • Successfully simulated gene regulatory networks (haematopoietic stem cell regulators) and signal transduction networks (Wnt/β-catenin signaling pathway).
  • Simulation results were consistent with those obtained from proprietary models, validating the framework's accuracy.
  • Demonstrated the framework's applicability to diverse biological network models.

Conclusions:

  • The developed framework effectively simulates BioPAX models, filling a critical gap in biological pathway analysis tools.
  • The framework's design ensures biological constraints are met during execution, leading to more reliable modeling.
  • The open-source Java implementation is readily available for researchers to use and adapt.
