Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

11.7K
Protein domains are small structurally independent units that are part of a single amino acid chain.  Although these domains are often structurally independent, they may rely on synergistic effects to perform their functions as part of a larger protein. Protein domains may be conserved within the same organism, as well as across different organisms.
A limited set of protein domains often duplicate and recombine during evolution. These domains can be organized in different combinations to...

Synthetic Biology

4.4K
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.

Proteins: From Genes to Degradation

11.9K
Within a biological system, the DNA encodes the RNA, and the nucleotide sequence in the RNA further defines the amino acid sequence in the protein. This is referred to as “The Central Dogma of Molecular Biology” - a term coined by Francis Crick.  Central dogma is a firm principle in biology that defines the flow of genetic information within any life form. The two fundamental steps in central dogma are - transcription and translation.
Transcription is the synthesis of RNA...

Structure-Activity Relationships and Drug Design

1.9K
Drug design is a dynamic field that involves discovering and developing new medications based on specific biological targets. This process heavily relies on structure-activity relationships (SAR) and quantitative structure-activity relationships (QSAR) to guide the design and optimization of efficient drugs.
SAR studies the intricate relationship between a drug's chemical structure and biological activity. It focuses on understanding how modifications to a drug's structure can influence...

Protein Modifications in the RER01:26

Protein Modifications in the RER

5.6K
Modification of secretory and transmembrane proteins entering the rough ER begins in the ER lumen. These modifications aid in protein folding and stabilize the acquired tertiary structure. Protein modifications in the rough ER co-occur at different stages of protein folding.
Broadly, these modifications can be categorized into four main categories — glycosylation, formation of disulfide bonds, assembly of protein subunits, and specific proteolytic cleavages like removal of signal...

Area of Science:

  • Biotechnology
  • Protein Engineering
  • Industrial Microbiology

Background:

  • Protein structure-guided redesign aims to improve enzyme properties.
  • Understanding the structural basis of biological characteristics is often limited.

Purpose of the Study:

  • To develop a novel protein redesign methodology.
  • To improve enzyme production levels in Aspergillus niger.

Main Methods:

  • A machine learning approach was used to identify beneficial mutations.
  • The method was applied to redesign an esterase and an inulinase.
  • Redesigned enzymes were produced in Aspergillus niger.

Main Results:

  • Up to 10-fold increase in production levels was achieved for two enzymes.
  • Enzyme activity was preserved with a small number of mutations.
  • Overly aggressive redesigns led to decreased production and activity.

Conclusions:

  • Protein redesign by learning is feasible and effective.
  • This method shows potential for improving industrial enzyme production.
  • The approach may be applicable to other protein design objectives.
