Those present in the RsaA protein may perform a similar function, since S-layer assembly and surface attachment requires calcium. These repeats are implicated in the binding of calcium for proper structure and biological activity of these proteins. Of particular interest was a specific region of the RsaA protein that was homologous to the repeat regions of glycine and aspartate residues found in several proteases and hemolysins. However, RsaA protein shared measurable homology with some exported proteins of other bacteria, including the hemolysins. A homology scan of the Swiss Protein Bank 17 produced no close matches to the predicted RsaA sequence. As with most other sequenced S-layer proteins, RsaA contained no cysteine residues.

Excepting aspartate, charged amino acids were in relatively low proportion, resulting in an especially acidic protein, with a predicted pI of 3.46. The predicted RsaA amino acid profile was unusual, with small neutral residues predominating.

Thus, no cleavage processing of the carboxy portion of the RsaA protein occurred during export, and with the exception of the removal of the initial methionine residue, the protein was not processed by cleavage to produce the mature protein. Protease cleavage of mature RsaA protein and amino acid sequencing of retrievable peptides yielded two peptides: one aligned with a region approximately two-thirds the way into the predicted amino acid sequence and the second peptide corresponded to the predicted carboxy terminus. The rsaA gene encoded a protein of 1026 amino acids, with a predicted molecular weight of 98 132.

Paul Stothard (of the University of Alberta, Canada) wrote the software suite (Stothard, 2000). This is a collection (which is why it is called a “suite”) of software, written in JavaScript1.5, for generating, formatting, and analyzing short DNA and protein sequences. In some places, the explanations may be verbatim. The original examples cited in the software suit (as “help” for explaining the programs) have been used here.

After completing this chapter, you will learn how to use some of the sequence analytical techniques using free online software called Sequence Manipulation Suite. The frequently used in silico analyses using molecular sequences are: sequence alignment determining conserved regions identification of low‐complexity region of nucleotides gene prediction nucleotide sequence assembling exploring biochemical and immunogenic properties of amino acid sequences protein structure prediction, and so on. Nucleotide and amino acid sequences are analyzed to understand their hidden features, to discover patterns, and to determine function, structure and their evolution.
