1 Bile acids stimulate ATP hydrolysis in the purified cholesterol transporter ABCG5/G8. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
2 Previous studies demonstrated that bile acids increased ABCG5/G8 specific cholesterol efflux in cell models. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
3 In this study we tested the effects of bile acids on ATP hydrolysis in Pichia pastoris purified ABCG5/G8 and found that they stimulated hydrolysis approximately 20-fold in wild-type ABCG5/G8 but not in a hydrolysis-deficient mutant. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
4 In this study we tested the effects of bile acids on ATP hydrolysis in Pichia pastoris purified ABCG5/G8 and found that they stimulated hydrolysis approximately 20-fold in wild-type ABCG5/G8 but not in a hydrolysis-deficient mutant. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
5 The data demonstrate that bile acids together with lipids and cholesterol increase ATP hydrolysis in purified ABCG5/G8. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
6 Bile acids may promote an active conformation of purified ABCG5/G8 either by global stabilization of the transporter or by binding to a specific site on ABCG5/G8. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
7 Bile acids may promote an active conformation of purified ABCG5/G8 either by global stabilization of the transporter or by binding to a specific site on ABCG5/G8. Bile Acids and Salts ATP binding cassette subfamily G member 5 Homo sapiens
