Adhesin Competence Regulator (<scene name='69/694230/Adcr_space_fill/1'>AdcR</scene>) is a transcriptional regulator that controls the activation of over seventy genes within the bacteria [https://en.wikipedia.org/wiki/Streptococcus_pneumoniae''Streptococcus pneumoniae''] and is a member of the multiple antibiotic resistance regulator (MarR) protein family <ref>DOI:10.1093/nar/gku1304 </ref>. Members of the [http://www.cell.com/current-biology/abstract/S0960-9822(13)00016-X MarR] protein family conserve a number of features including a general triangular shape, a two fold pseudosymmetric homodimer, and a winged helix-turn-helix pattern [https://en.wikipedia.org/wiki/Helix-turn-helix (wHTH)] which can be seen in Figure 1. AdcR exhibits these conserved features as well while also exhibiting its own distinct features. | Adhesin Competence Regulator (<scene name='69/694230/Adcr_space_fill/1'>AdcR</scene>) is a transcriptional regulator that controls the activation of over seventy genes within the bacteria [https://en.wikipedia.org/wiki/Streptococcus_pneumoniae''Streptococcus pneumoniae''] and is a member of the multiple antibiotic resistance regulator (MarR) protein family <ref name="Sanson">DOI:10.1093/nar/gku1304 </ref>.

Streptococcus pneumoniae, the host to AdcR, is a significant pathogenic bacterium. Although asymptomatic in healthy individuals, S. pneumoniae can lead to Bronchitis, meningitis conjunctivitis, or brain abscesses in those with weaker immune systems. Host regulation of zinc is often used to combat pathogens such as S. pneumoniae. A better understanding of AdcR, the regulator that controls the transcription of zinc specific uptake transporters, could | Streptococcus pneumoniae, the host to AdcR, is a significant pathogenic bacterium.

A better understanding of AdcR, the regulator that controls the transcription of zinc specific uptake transporters, could help to illuminate better mechanism for combating not only S. pneumoniae, but other comparable bacteria. | ||
