<p>Previously to the study of the codifying nucleotide glmS sequences, Glms protein was analyzed to check the reported high level of conservation of the C-terminal part of this protein (<a href="http://www.sciencedirect.com/science/article/pii/S0167483802003187" target="_blank">Milewski, 2002</a>). Thus, a multialignment, a circular and squared tree and several logos of all the downloaded Glms sequences were obtained (figure 5). It is mentionable the high level of conservation found in the last 15 amino acids of this protein in all organisms which contrast with the lack of any conservation in the previous amino acidic sequence (this difference is perfectly shown in all sequence logos). It is also interesting that the consensus sequence of this C-terminal part of Glms protein match perfectly with the amino acidic sequence resulting when translating the nucleotide consensus obtained in figure 3.</p>

<p>After the conservational study of the Glms protein sequence, some glmS gene codifying sequences (those representing the main groups and model organisms) were also aligned to elucidate the level of conservation of the attTn7 insertion site (figure 9.A). In this case, the level of conservation was much lower than observed at protein level. Moreover, a logo was obtained for this nucleotide sequence range (figure 9.B), whose sequence was also translated. In this logo (as in the logo obtained for the organisms with Tn7 family transposon) the first two positions at each codon were conserved, showing a strong variation at the ‘wobble’ position. This result was expected because it corresponds to a codifying sequence. When comparing this last logo sequence with the logo sequence obtained for the sequences of organisms with the Tn7 system (figure 10) it is surprisingly the high level of similarity founded. </p>
