1 Modification of apo-E2 with cysteamine, which converts the cysteine at position 158 to a positively charged lysine analogue, activates receptor binding approximately 13-fold. Cysteamine apolipoprotein E Homo sapiens
2 When the Mr = 22,000 fragment was modified with cysteamine and combined with DMPC, receptor binding was further enhanced, attaining the level of activity of normal apo-E3 X DMPC, a 100-fold increase over apo-E2 X DMPC binding. Cysteamine apolipoprotein E Homo sapiens
3 When the Mr = 22,000 fragment was modified with cysteamine and combined with DMPC, receptor binding was further enhanced, attaining the level of activity of normal apo-E3 X DMPC, a 100-fold increase over apo-E2 X DMPC binding. Cysteamine apolipoprotein E Homo sapiens
4 The receptor binding of apo-E2-containing beta-very low density lipoproteins could also be activated by cysteamine treatment, with the same retention of enhanced binding activity occurring after the reversal of the modification. Cysteamine apolipoprotein E Homo sapiens
