Summary
Cells require functions for discrimination, managing information, and coordinated growth. CTP synthetase coordinates growth, and its metabolite provides antiviral defense against viruses in all life domains.
Area of Science:
- Cellular biology
- Synthetic biology
- Genomics
Background:
- Minimal genome assembly reveals genes with unknown functions.
- Cells possess inherent error-proneness and aging processes.
- Information management is crucial for cellular discrimination and homeostasis.
Purpose of the Study:
- To identify and categorize overlooked cellular functions.
- To elucidate the role of CTP synthetase in cellular growth.
- To explore cellular antiviral defense mechanisms.
Main Methods:
- Analysis of minimal genome data.
- Investigating cellular discrimination mechanisms.
- Studying metabolic pathways and growth regulation.
- Examining antiviral strategies.
Main Results:
- Identified three key overlooked functional categories: discrimination, information management, and growth.
- CTP synthetase identified as a coordinator of nonhomothetic growth.
- Discovered 3'-deoxy-3',4'-didehydro-CTP as an antiviral metabolite across all domains of life.
Conclusions:
- Understanding these functions is critical for synthetic biology chassis engineering.
- Cellular growth and defense mechanisms are intertwined.
- Metabolic adaptations provide robust antiviral immunity.

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.

141
Biosynthesis in bacteria is a fundamental anabolic process that generates essential macromolecules, including proteins, nucleic acids, lipids, and polysaccharides. These macromolecules are critical for cellular growth, replication, and function. The process is tightly regulated and energetically linked to catabolic pathways to ensure optimal resource utilization.Biosynthetic pathways begin with precursor metabolites such as pyruvate, acetyl-CoA, and glucose-6-phosphate derived from glycolysis,...

Prokaryotes are small unicellular organisms that include the domains—Archaea and Bacteria. Bacteria include many common organisms, such as Salmonella and E. coli, while the Archaea include extremophiles that live in harsh environments, such as volcanic springs.
Like eukaryotic cells, all prokaryotic cells are surrounded by a plasma membrane, have genetic material in the form of single, circular DNA, a cytoplasm that fills the interior of the cell, and ribosomes that synthesize proteins....

01:15What are Cells?
40.6K
Cells are the smallest and basic units of life, whether it is a single cell that forms the entire organism, e.g., in a bacterium, or trillions of them, e.g., in humans. No matter what organism a cell is a part of, they share specific characteristics.
Basic Characteristics of Cells
A living cell has a plasma membrane, a bilayer of lipids that separates the aqueous solution inside the cell called the cytoplasm from the outside environment.
Furthermore, a living cell possesses genetic information...

The cell is chemically composed of water, organic molecules and inorganic ions.
Water
The polarity of the water molecule and its resulting hydrogen bonding makes water a unique substance with special properties that are intimately tied to the processes of life. Life originally evolved in an aqueous environment, and most of an organism’s cellular chemistry and metabolism occur inside the aqueous contents of the cell’s cytoplasm. Special properties of water are its high heat capacity...

01:24Other Glycolytic Pathways
284
The pentose phosphate pathway (PPP) operates in parallel with glycolysis, facilitating the metabolism of both pentoses and glucose. This pathway consists of two distinct phases: the oxidative and non-oxidative phases. While it does not directly generate ATP, the intermediates formed during the process can integrate into glycolysis, contributing to cellular energy metabolism when required.Oxidative Phase: NADPH ProductionThe oxidative phase of the pentose phosphate pathway is primarily...
