Dimyristoylphosphatidylcholine 198-202 apolipoprotein C1 Homo sapiens 82-88 18984910-5 2009 In contrast to wild-type apoC-I (WT), which binds DMPC vesicles with an apparent Kd [Kd(app)] of 0.89 microM, apoC-I(F42A) and apoC-I(F46A) possess 2-fold weaker affinities for DMPC with Kd(app) of 1.52 microM and 1.58 microM, respectively. Dimyristoylphosphatidylcholine 50-54 apolipoprotein C1 Homo sapiens 25-31 18984910-5 2009 In contrast to wild-type apoC-I (WT), which binds DMPC vesicles with an apparent Kd [Kd(app)] of 0.89 microM, apoC-I(F42A) and apoC-I(F46A) possess 2-fold weaker affinities for DMPC with Kd(app) of 1.52 microM and 1.58 microM, respectively. Dimyristoylphosphatidylcholine 177-181 apolipoprotein C1 Homo sapiens 25-31 18984910-6 2009 However, apoC-I(F46G), apoC-I(F42A/F46A), apoC-I(F42G), and apoC-I(F42G/F46G) bind significantly weaker to DMPC with Kd(app) of 2.24 microM, 3.07 microM, 4.24 microM, and 10.1 microM, respectively. Dimyristoylphosphatidylcholine 107-111 apolipoprotein C1 Homo sapiens 9-15 18984910-6 2009 However, apoC-I(F46G), apoC-I(F42A/F46A), apoC-I(F42G), and apoC-I(F42G/F46G) bind significantly weaker to DMPC with Kd(app) of 2.24 microM, 3.07 microM, 4.24 microM, and 10.1 microM, respectively. Dimyristoylphosphatidylcholine 107-111 apolipoprotein C1 Homo sapiens 23-29 18984910-6 2009 However, apoC-I(F46G), apoC-I(F42A/F46A), apoC-I(F42G), and apoC-I(F42G/F46G) bind significantly weaker to DMPC with Kd(app) of 2.24 microM, 3.07 microM, 4.24 microM, and 10.1 microM, respectively. Dimyristoylphosphatidylcholine 107-111 apolipoprotein C1 Homo sapiens 23-29 18984910-6 2009 However, apoC-I(F46G), apoC-I(F42A/F46A), apoC-I(F42G), and apoC-I(F42G/F46G) bind significantly weaker to DMPC with Kd(app) of 2.24 microM, 3.07 microM, 4.24 microM, and 10.1 microM, respectively. Dimyristoylphosphatidylcholine 107-111 apolipoprotein C1 Homo sapiens 23-29 18984910-7 2009 Sedimentation velocity studies subsequently show that the protein/DMPC complexes formed by these apoC-I mutants sediment at 6.5S, 6.7S, 6.5S, and 8.0S, respectively.
