De novo design of potent antimicrobial peptides.
Lipopolysaccharide (LPS), shed by gram-negative bacteria during infection and antimicrobial therapy, may lead to lethal endotoxic shock syndrome. A rational design strategy based on the presumed mechanism of antibacterial effect was adopted to design cationic antimicrobial peptides capable of binding to LPS through tandemly repeated sequences of alternating cationic and nonpolar residues. The p...
متن کاملMetal Stabilization of Collagen and de Novo Designed Mimetic Peptides.
We explore the design of metal binding sites to modulate triple-helix stability of collagen and collagen-mimetic peptides. Globular proteins commonly utilize metals to connect tertiary structural elements that are well separated in sequence, constraining structure and enhancing stability. It is more challenging to engineer structural metals into fibrous protein scaffolds, which lack the extensi...
متن کاملClustering of Short Read Sequences for de novo Transcriptome Assembly
Given the importance of transcriptome analysis in various biological studies and considering thevast amount of whole transcriptome sequencing data, it seems necessary to develop analgorithm to assemble transcriptome data. In this study we propose an algorithm fortranscriptome assembly in the absence of a reference genome. First, the contiguous sequencesare generated using de Bruijn graph with d...
متن کاملDe-Novo Design of Antimicrobial Peptides for Plant Protection
This work describes the de-novo design of peptides that inhibit a broad range of plant pathogens. Four structurally different groups of peptides were developed that differ in size and position of their charged and hydrophobic clusters and were assayed for their ability to inhibit bacterial growth and fungal spore germination. Several peptides are highly active at concentrations between 0,1 and ...
متن کاملTowards Rational de novo Design of Peptides for Inorganic Interfaces
Protein adsorption at inorganic surfaces is highly relevant to nanoand bionanotechnology. Just two examples of great significance are the use of specific peptide sequences to control cell deposition on tissue scaffolds, and the tethering of bio-photosynthetic reaction centers on electrodes to harvest light for power generation and hydrogen production. Understanding of the behavior of proteins i...
