Analysis of protein chameleon sequence characteristics [PDF]

Bioinformation, 2009
Conversion of local structural state of a protein from an alpha-helix to a beta-strand is usually associated with a major change in the tertiary structure. Similar changes were observed during the self assembly of amyloidogenic proteins to form fibrils, which are implicated in severe diseases conditions, e.g., Alzheimer disease. Studies have emphasized

BMC Caller: a webtool to identify and analyze bacterial microcompartment types in sequence data

Biology Direct, 2022
Bacterial microcompartments (BMCs) are protein-based organelles found across the bacterial tree of life. They consist of a shell, made of proteins that oligomerize into hexagonally and pentagonally shaped building blocks, that surrounds enzymes ...

Integrative visual analysis of protein sequence mutations [PDF]

BMC Proceedings, 2014
An important aspect of studying the relationship between protein sequence, structure and function is the molecular characterization of the effect of protein mutations. To understand the functional impact of amino acid changes, the multiple biological properties of protein residues have to be considered together.Here, we present a novel visual approach ...

Species-specific analysis of protein sequence motifs using mutual information

BMC Bioinformatics, 2005
Background Protein sequence motifs are by definition short fragments of conserved amino acids, often associated with a specific function. Accordingly protein sequence profiles derived from multiple sequence alignments provide an alternative description ...

Filtering Degenerate Patterns with Application to Protein Sequence Analysis

Algorithms, 2013
In biology, the notion of degenerate pattern plays a central role for describing various phenomena. For example, protein active site patterns, like those contained in the PROSITE database, e.g., [FY ]DPC[LIM][ASG]C[ASG], are, in general, represented by ...
