Diversity of Archaea IV01:29

Diversity of Archaea IV

595
Hyperthermophilic archaea are a group of extremophiles thriving at temperatures above 80°C, often in hydrothermal vents and volcanic soils where conditions surpass the boiling point of water. At such temperatures, proteins, membranes, and DNA in most organisms degrade, but hyperthermophiles have evolved remarkable adaptations to maintain stability and function.Unique Cellular FeaturesHyperthermophilic membranes are composed of a monolayer of biphytanyl tetraether lipids, which resist...

Diversity of Archaea III

438
Crenarchaeota, a prominent phylum of Archaea, is remarkable for its ability to thrive in extreme environments characterized by high temperatures and acidity. These microorganisms inhabit sulfuric hot springs, volcanic systems, and submarine hydrothermal vents, where temperatures often exceed 100°C. The unique adaptations of Crenarchaeota not only allow survival under such extreme conditions but also provide insights into the mechanisms of life in primordial Earth-like...

Intrinsically Disordered Proteins

21.7K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Regulation of the Unfolded Protein Response

3.2K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...

Area of Science:

  • Protein engineering
  • Computational biology
  • Biochemistry

Background:

  • Engineering proteins with specific structures and functions remains challenging.
  • Rational protein engineering aims to improve protein properties like stability and activity through structural modification.
  • In silico strategies for enhancing protein stability are not yet extensively explored, despite known contributing factors.

Purpose of the Study:

  • To present the iRDP web server, a unified platform for rational protein engineering.
  • To provide tools for selecting target proteins based on stability factors.
  • To enable in silico prediction of stabilizing mutations and assessment of mutants.

Main Methods:

  • Development of the iRDP web server with three modules: iCAPS, iStability, and iMutants.
  • iCAPS: Selection of target proteins based on structural stability factors.
  • iStability: In silico implementation of thermostabilization strategies for mutation identification and stability prediction.
  • iMutants: Assessment of mutants based on local interaction networks and residue conservation.

Main Results:

  • The iRDP web server offers a unified platform for rational protein engineering.
  • iCAPS facilitates target protein selection.
  • iStability predicts stabilizing mutations and protein stability.
  • iMutants evaluates mutations based on network properties and conservation.
