Database similarity searching is an essential technique in bioinformatics as it allows us to characterize newly determined sequences by comparing them to existing databases<\/a>.<\/p>\n\n\n\n

FASTA is one of the first widely-used database similarity search tools. FASTA (or FastA), an abbreviation for \u2018Fast-All\u2019, is a sequence alignment tool that takes nucleotide or protein sequences as input and compares it with existing databases.<\/strong> It was first developed by David J. Lipman and William R. Pearson in 1985 and has since been refined and adapted for various applications.<\/p>\n\n\n\n

The text-based file format for representing nucleotide or protein sequences, which originates from the FASTA program, has now become a standard in bioinformatics. Many other sequence database search tools also use the FASTA file format.<\/p>\n\n\n\n
