Evolution Of The Kinetics And Dynamics Of Heme-Crevice Loop Regulating Chemistry In Human Cytochrome C, Shiloh M. Nold
Graduate Student Theses, Dissertations, & Professional Papers
Cytochrome c, cytc, is a metalloprotein that plays primary roles in electron transport and intrinsic apoptotic pathways. Much of the chemistry that cytc is involved with is regulated by a highly conserved region known as the heme crevice loop, consisting of residues 70-85. Only three of these residues (those at positions 81, 83 and 85) are not universally conserved within the evolutionary timeline. Here I look to elucidate possible evolutionary roles for several of the key residues known to be important in regulating heme chemistry of cytc.
I first address the role that lysine 72 plays in ...
