Allosteric effector Flashcards
BPG acts as what
an allosteric effector
Binding of BPG acts to lower what
oxygen affinity to hemoglobin
BPG binds where in the B chains and does what
BPG binds in the cavity between the β chains, making electrostatic interactions with positively charged residues around the opening
BPG can only bind to what form
deoxyHb form the cavity in the oxyHb form is because the cavity in the oxyHb form is to small to accommodate BPG.
The higher the BPG in red blood cells the what
the more stable deoxyHb and decrease in O2 affinity
Sickle Cell Anemia
Is a genetic disorder caused by a single amino acid substitution (Glu6 to Val6) in each β-chain of hemoglobin.The change introduces hemoglobin. The change introduces a hydrophobic patch on the surface of hemoglobin that causes molecules to aggregate into bundles of fibres
