MSA are completed where homologous sequences are compared in order to perform phylogenetic reconstruction, protein secondary and tertiary structure analysis, and protein function prediction analysis [1]. Biologically good and accurate alignments can have significant meaning, showing relationships and homology...

for each protein on a single line, with gaps (“–”) inserted such that “equivalent” residues appear in the same column. The precise meaning of equivalence is generally context dependent: for the phylogeneticist, equivalent residues have common evolutionary ancestry; for the structural biologist...
The degree of conservation can also be given as a number for either an individual sequence location or the entire sequence with larger numbers meaning a higher degree of conservation. Finally, as shown in the figure, color can be used to indicate the physico-chemical properties of the amino ...
In a previous paper, we introduced MUSCLE, a new program for creating multiple alignments of protein sequences, giving a brief summary of the algorithm and showing MUSCLE to achieve the highest scores reported to date on four alignment accuracy benchmark

This suggests that the conserved sequence domains are stably captured through alignment upgrades. Although most of the type 2 segments in release 6 remain in release 7, the later version has signi"cantly more/longer type 2 segments, meaning that the new multi- alignment contains more gap ...
conservation of the reading frame and absence of stop codons. RNAcode does not rely on any species specific sequence characteristics whatsoever and does not use any machine learning techniques. The only input required for RNAcode is a multiple sequence alignment either in MAF or Clustal W format....
thermophila-specific, meaning that they do not have identifiable known homologs in any other organism. However, all three possess clusters of glutamines in their primary sequence suggestive of a role in transcription [30]. The fifth protein SAINTexpress analysis revealed to co-purify with Snf5Tt-...
Then, we found the orthologous proteins of these species in each group with human proteins, and we performed a multiple sequence alignment with Clustal-omega56. Finally, we used the rate4site software to calculate the evolutionary rate of each human phosphosite in the three groups, respectively...
