Working Together: Using Protein Networks Of Bacterial Species To Compare Essentiality, Centrality, And Conservation In Escherichia Coli., Christopher Wimble

Theses and Dissertations

Proteins in Escherichia coli were compared in terms of essentiality, centrality, and conservation. The hypotheses of this study are: for proteins in Escherichia coli, (1) there is a positive, measureable correlation between protein conservation and essentiality, (2) there is a positive relationship between conservation and degree centrality, and (3) essentiality and centrality also have a positive correlation. The third hypothesis was supported by a moderate correlation, the first with a weak correlation, and the second hypotheis was not supported. When proteins that did not map to orthologous groups and proteins that had no interactions were removed, the relationship between essentality …
