Exam 2 Flashcards
the major signal sequence in Mitochondrial Amphiphilic alpha helix
Cytochrome oxidase subunit 4
amphiphilic alpha helix is formed from?
N terminal and internal signal sequences in the Mitochondria
TIM 22 and 23 complexes are localized in which mitochondrial compartment?
the inner mitochondrial membrane and extend into intermembrane space.
TOM complexes are present in? function?
outer membrane of the mitochondria.
import all nucleus encoded proteins
protein import into mitochondrial matrix is inserted into the membrane by?
TOM complex
TOM transports protein across the which membranes?
outer to inner membrane space.
in the inner membrane space, the protein binds to this complex and allows to move through the channel to the matrix
TIM complex
ATP strips off these molecules in protein transport into M. matrix
cytosolic heat shock protein chaperones
why does it go through the TOM and then the SAM complex?
the recognition process and the pulling in process. then the insertion process by SAM.
the second sequence is hydrophobic. T/F?
true. allows it to stick to the inner membrane space
the hydrophobic sequence is recognized on the second sequence by?
the OXA complex
Mia 40 forms what kind of bonds from the incoming protein to the intermembrane space?
disulfide bonds with abundant Cysteine residues on them.
ATP, ADP, and Phosphate transporters got though which complex?
TIM 22 complex
Pancreatic cells have a lot of?
rough ER for protein synthesis
the red thingy is the ER sequence…..
