How do you analyze a protein sequence?

How do you analyze a protein sequence?

The two major direct methods of protein sequencing are mass spectrometry and Edman degradation using a protein sequenator (sequencer). Mass spectrometry methods are now the most widely used for protein sequencing and identification but Edman degradation remains a valuable tool for characterizing a protein’s N-terminus.

What are sequence analysis tools?

A graphical analysis tool that finds all open reading frames in a user’s sequence or in a sequence already in the database. Sixteen different genetic codes can be used. The deduced amino acid sequence can be saved in various formats and searched against protein databases using BLAST.

What is BLAST program?

In bioinformatics, BLAST (basic local alignment search tool) is an algorithm and program for comparing primary biological sequence information, such as the amino-acid sequences of proteins or the nucleotides of DNA and/or RNA sequences.

What is the difference between blastn and Blastp?

The amino acid sequences being identical, blastp would have no problem in retrieving one sequence, using the other sequence as query. Blastn, however, uses a default word size of 11 nucleotides. This means the two sequences must match with at least 11 nucleotides for blastn to be able to report any hit at all.

What is the difference between BLAST and FASTA?

The main difference between BLAST and FASTA is that BLAST is mostly involved in finding of ungapped, locally optimal sequence alignments whereas FASTA is involved in finding similarities between less similar sequences.

What is the Expasy tool in bioinformatics?

Expasy is an extensible and integrative portal including >160 databases and software tools developed by SIB groups. It covers a wide range of fields in life sciences and biomedical research, spanning genomics, proteomics, structural biology, evolution, phylogeny, systems biology and medicinal chemistry.
