Protein-protein Interfaces

15.0K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Cis-regulatory Sequences

12.1K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Ribosome Profiling02:24

Ribosome Profiling

4.3K
Ribosome profiling or ribo-sequencing is a deep sequencing technique that produces a snapshot of active translation in a cell. It selectively sequences the mRNAs protected by ribosomes to get an insight into a cell’s translation landscape at any given point in time.
Applications of ribosome profiling
Ribosome profiling has many applications, including in vivo monitoring of translation inside a particular organ or tissue type and quantifying new protein synthesis levels.
The technique...

Area of Science:

  • Biotechnology
  • Molecular Biology
  • Bioinformatics

Background:

  • Saturation mutagenesis is crucial for protein engineering.
  • The NNK degenerate codon method is common but has limitations including amino acid bias and wild-type inclusion.
  • These limitations increase library size and screening efforts.

Purpose of the Study:

  • To introduce DYNAMCC, an algorithm for codon compression.
  • To develop a user-friendly web interface for DYNAMCC.
  • To provide a more accessible and efficient alternative to NNK for saturation mutagenesis.

Main Methods:

  • Developed DYNAMCC algorithms for codon compression.
  • Ensured minimal degenerate codon sets with no off-target or wild-type codons.
  • Implemented redundancy control.
  • Created a web-based interface for the DYNAMCC algorithms.

Main Results:

  • DYNAMCC algorithms identify minimal degenerate codon sets for targeted amino acid coverage.
  • The method eliminates off-target codons and controls redundancy.
  • Experimental validation confirmed advantages over the NNK method.
  • A user-friendly web interface (www.dynamcc.com) has been launched.

Conclusions:

  • DYNAMCC provides a superior codon compression strategy for saturation mutagenesis.
  • The web interface enhances accessibility for researchers without computational expertise.
  • This approach reduces library size and downstream screening load in protein engineering.
