Graduate Theses and Dissertations
In previous work from this laboratory, methionine containing peptides from the human urinary proteome were examined by mass spectrometry for the degree of methionine oxidation to the sulfoxide form. While this demonstrated that many of the methionines detected were capable of being oxidized, the question of whether these methionines are important in the structure and/or function of the parent proteins came about. In some proteins, methionine oxidation has been linked to conformational changes and alteration of function and thus can serve as a mechanism for reversible regulation of activity. It is hypothesized that methionines which might serve a regulatory purpose …
