Protein sequence alignments in twilight zone. Protein sequences fold into unique three-dimensional (3D ) structures. However proteins with similar sequences adopt similar structures 1 2 3
2002-4-1 · The current sequence Z is added to the alignment with a new sequence designated as Z for the next cycle of the iteration. Placement of the motif in sequence Z becomes more and more refined each iteration and the complete sequence alignment (i.e. the placement of the motif s starting point in each sequence) eventually converges.
2020-6-29 · 6.1 Spike protein features. Before attempting an alignment of the SARS_CoV-2 spike protein to other similar structure let s look at a summary of the the spike protein sequence features. Figure 1 of Lokman et al. provides a graphical comparison between SARS_CoV and SARS-CoV-2 spike sequence

2019-11-7 · Pairwise Sequence Alignment is used to identify regions of similarity that may indicate functional structural and/or evolutionary relationships between two biological sequences (protein or nucleic acid). By contrast Multiple Sequence Alignment (MSA) is the alignment of three or more biological sequences of similar length. From the output of MSA applications homology can be inferred and the evolutionary relationship between the sequences
2009-4-30 · Protein sequence alignment is the task of identifying evolutionarily or structurally related positions in a collection of amino acid sequences. Although the protein alignment problem has been studied for several decades many recent studies have demonstrated
Motivation From evolutionary interference function annotation to structural prediction protein sequence comparison has provided crucial biological insights. While many sequence alignment algorithms have been developed existing approaches often cannot detect hidden structural relationships in the "twilight zone" of low sequence identity.
