Genome Size and the Evolution of New Genes

Genome Size and the Evolution of New Genes

While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.

Biosynthesis in Bacteria

Biosynthesis in Bacteria

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,...

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.

Gene Evolution - Fast or Slow?

The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.
In contrast, regions which code...

Area of Science:

Biochemistry
Synthetic Biology
Natural Product Chemistry

Background:

Modular polyketide synthases (PKS) assemble complex natural products like erythromycin, avermectin, and rapamycin via enzymatic assembly lines.
Engineering PKS genes for novel analogues is often slow, inefficient, and yields low amounts of product.

Purpose of the Study:

To develop a rapid method for recombining PKS gene clusters to create diverse and highly productive assembly lines.
To accelerate the discovery of novel polyketide natural products.

Main Methods:

A novel recombination method was employed to rapidly modify PKS gene clusters, enabling the replacement, addition, or removal of enzymatic modules.
The method was demonstrated using the rapamycin biosynthetic gene cluster.

Main Results:

The recombination method generated diverse PKS assembly lines with high frequency and productivity.
Multiple strains producing novel rapamycin-related polyketides were isolated in a single experiment.
Sequence analysis provided insights into designing synthetic PKS assembly lines.

Conclusions:

This method significantly accelerates the natural evolution of modular PKS, enabling rapid generation of novel polyketides.
The approach offers a powerful tool for synthetic biology and drug discovery, facilitating the construction of efficient, custom-designed enzymatic assembly lines.
