The Central Dogma01:20

The Central Dogma

21.8K
The central dogma explains the flow of genetic information from DNA nucleotides to the amino acid sequence of proteins.
RNA is the Missing Link Between DNA and Proteins
In the early 1900s, scientists discovered that DNA stores all the information needed for cellular functions and that proteins perform most of these functions. However, the mechanisms of converting genetic information into functional proteins remained unknown for many years. Initially, it was believed that a single gene is...

Exon Recombination02:32

Exon Recombination

3.6K
The evolution of new genes is critical for speciation. Exon recombination, also known as exon shuffling or domain shuffling, is an important means of new gene formation. It is observed across vertebrates, invertebrates, and in some plants such as potatoes and sunflowers. During exon recombination, exons from the same or different genes recombine and produce new exon-intron combinations, which might evolve into new genes. 
Exon shuffling follows “splice frame rules.” Each exon...

Genome Size and the Evolution of New Genes

8.0K
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.

Conservative Site-specific Recombination and Phase Variation02:53

Conservative Site-specific Recombination and Phase Variation

6.0K
Because the DNA segments are cut and reorganized in a direction-specific manner, site-specific recombination has emerged as an efficient genetic engineering technique. Flippase and Cyclization recombinases or Flp and Cre, respectively, are two members of the tyrosine recombinase family derived from bacteriophages, that are used to mediate site-specific DNA insertions, deletions, and targeted expression of proteins in mammalian cell lines.
The recognition sites for Cre recombinase called LoxP...

Synthetic Biology02:55

Synthetic Biology

4.8K
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.

Area of Science:

  • Biochemistry
  • Protein Engineering
  • Synthetic Biology

Background:

  • Enzyme design is a key area of computational protein design (CPD).
  • Noncanonical amino acids (ncAAs) offer expanded chemical diversity for protein engineering.
  • Genetic code expansion enables in vivo incorporation of ncAAs using engineered aminoacyl-tRNA synthetases (aaRSs) and tRNAs.

  • This review examines the application of CPD to overcome limitations of experimental directed evolution in enzyme design.
  • Focuses on redesigning aaRSs and engineering new protein functionalities using ncAAs.
  • Highlights method developments like adaptive landscape flattening Monte Carlo for enzyme redesign targeting substrate or transition state binding.

Key Points:

  • Directed evolution has successfully incorporated over 200 ncAAs but has limitations, especially for noncanonical amino acid backbones.
  • CPD offers a powerful approach to address these limitations in genetic code expansion and enzyme engineering.
  • CPD facilitates the design of novel enzymes with enhanced functionalities by incorporating diverse ncAAs.

Conclusions:

  • CPD is crucial for advancing enzyme design and genetic code expansion.
  • The integration of ncAAs through CPD opens new avenues for creating bespoke proteins with tailored functions.
  • Future research should focus on further developing CPD methodologies for complex enzyme engineering tasks.
