Calcium independent reciprocal molar partition coefficients for syt1 C2B and C2AB to PC:PS (3:1) or PC/PS/PIP2 (74:25:1) membranes†

C2A C2B C2AB
PC:PS:PIP2 - 9.6(±1.1) × 102 9.1(±1.6) × 102
PC:PS - 2.9(±0.3) × 102 1.2(±0.1) × 102
†

Partition coefficients determined by sedimentation (see Methods) in the presence of 1 mM EGTA. Partition coefficients to PC:PS in the absence of Ca2+ are shown for comparison and were published previously (13).
