Synthetic Biology

Synthetic Biology

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.

Protein Networks

Protein Networks

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

A Single-Component System

A Single-Component System

In the field of chemistry, the terms "component" and "phase" hold significant importance. A component refers to a chemically distinct substance in a system that has specific properties. It is chemically homogeneous, meaning it has the same properties throughout. For example, in a mixture of salt and water, both salt and water are considered separate components because they have different chemical properties.On the other hand, a phase is a form of matter that has a consistent chemical...

Single molecule: Single molecules meet systems biology.

|September 10, 2010

Summary

Single-molecule methods reveal genome-wide mRNA and protein levels in bacteria. This provides a systems-level view of gene expression and protein production dynamics.

Area of Science:

Microbiology
Molecular Biology
Systems Biology

Background:

Traditional methods often average gene expression across populations, masking cell-to-cell variability.
Understanding the interplay between mRNA and protein at the single-cell level is crucial for deciphering bacterial regulatory networks.

Discussion:

Single-molecule assays enable simultaneous measurement of mRNA and protein abundance within individual bacterial cells.
This approach allows for the direct observation of correlations and dynamics between transcription and translation.
The data provides insights into post-transcriptional regulation and protein stability in heterogeneous bacterial populations.

Key Insights:

Developed and applied single-molecule techniques for comprehensive analysis of bacterial gene expression.
