Mutagenesis-Based Active-Site Characterization Of The Diabetes Drug Target Mitoneet, Lisa Mickley

Williams Honors College, Honors Research Projects

This project investigates the cluster stability of an outer mitochondrial membrane protein mitoNEET under mutational stress and drug binding analysis. MitoNEET is a part of a class of proteins that coordinate an Fe-S molecule into its tertiary structure. This protein is believed to facilitate the oxidative capacity of the electron transport chain by reversible loss of its coordinated Fe-S molecule. The research of this paper uses site directed protein mutagenesis to selectively alter the three cysteine, one histidine cluster coordination into more common coordination patterns such as two cysteine, two histidine or four cysteine. The ultimate goal is to optimize …
