Conservation of Protein Domains Over Different Proteins02:26

Conservation of Protein Domains Over Different Proteins

15.3K
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...

Detergent Purification of Membrane Proteins

7.2K
Detergents are used to purify the integral proteins of the membrane. The hydrophobic portion of the detergent can replace membrane phospholipids while solubilizing the membrane proteins. When detergent monomers reach a specific concentration in a solution called critical micelle concentration (CMC), they form micelles. Above CMC, the concentration of the detergent monomers remains in equilibrium with the micelle. The number of detergent monomers present in the CMC varies for each detergent, and...

  • To improve the speed and sensitivity of protein family identification.

Main Methods:

  • Implementation of the 'Mosaic Matching' algorithm within the UProC toolbox.
  • Large-scale sequence analysis.
  • Metagenome simulation studies using unassembled short reads.

Main Results:

  • UProC achieves speeds three orders of magnitude faster than profile-based methods.
  • Demonstrated up to 80% higher sensitivity on 100 bp reads in metagenome simulations.
  • Provides a novel, efficient approach for protein classification.

Conclusions:

  • UProC offers a significant advancement in handling large-scale biological sequence data.
  • The 'Mosaic Matching' algorithm provides a powerful tool for rapid and sensitive protein family identification.
  • UProC is a valuable open-source resource for the bioinformatics community.
