Tryptophan 17-27 HDL3 Homo sapiens 54-58 18004880-1 2007 In the minor fraction of HDL3 containing alpha-tocopherol (alphaTocOH), selective one-electron oxidation of Trp and Tyr residues of apolipoproteins A-I and A-II by *Br2- radical-anions produces the corresponding semioxidized species, TyrO* and *Trp. Tryptophan 108-111 HDL3 Homo sapiens 25-29 18004880-1 2007 In the minor fraction of HDL3 containing alpha-tocopherol (alphaTocOH), selective one-electron oxidation of Trp and Tyr residues of apolipoproteins A-I and A-II by *Br2- radical-anions produces the corresponding semioxidized species, TyrO* and *Trp. Tryptophan 245-248 HDL3 Homo sapiens 25-29 18004880-5 2007 In the major fraction of HDL3 particles lacking alphaTocOH, TyrO* and *Trp are repaired by free and HSA-bound quercetin. Tryptophan 71-74 HDL3 Homo sapiens 25-29 17411073-11 2007 Western blots of gamma-irradiated HDL3 comparable to those reported for apoAI myeloperoxidase oxidation show that the incomplete repair of semioxidized Tyr and Trp induces apoAI and apoAII permanent damage including formation of a heterodimer of one apoAI with a monomeric apoAII at about 36 kDa. Tryptophan 160-163 HDL3 Homo sapiens 34-38 2302415-7 1990 Owing to the intricate contact between the lipidic core and the apolipoproteins, the Trp residues of human serum LDL and HDL3 are very rapidly oxidized, i.e., at least one order of magnitude faster than Tyr HDL and Lys LDL, which are believed to be involved in the binding of these lipoproteins to their cell receptors. Tryptophan 85-88 HDL3 Homo sapiens 121-125 17411073-0 2007 Interplay of oxygen, vitamin E, and carotenoids in radical reactions following oxidation of Trp and Tyr residues in native HDL3 apolipoproteins. Tryptophan 92-95 HDL3 Homo sapiens 123-127 9555005-2 1998 Oxidation of HDL3 was monitored by measuring the following parameters: (i) formation of conjugated dienes, (ii) production of thiobarbituric acid reactive substances (TBARS), (iii) decrease in reactive lysine and (iv) tryptophan residues, (v) change in particle charge and (vi) diameter, and (vii) oligomerisation of apoA-I and apoA-II.
