Analysis of the Partitioning Behavior of Horseradish Peroxidase to Phospholipid and Surfactant Membranes

摘要

The partitioning behavior of horseradish peroxidase (HRP) to phospholipid- and surfactant vesicles has been analyzed. Peripheral binding of the zwitterionic phospholipid vesicle membranes is proposed with insertion into the membrane interior of negatively charged surfactant vesicles, resulting from non-electrostatic interaction. The insertion of HRP is interpreted by considering the interaction between headgroups of phospholipid and between headgroups of surfactant.
