Effect of phosphatidylcholine vesicles on the activity of DNA polymerase-alpha

Mol Cell Biochem. 1979 Nov 1;27(3):135-8. doi: 10.1007/BF00215361.

Abstract

Phosphatidylcholine vesicles stimulate the activity of the DNA polymerase-alpha from calf thymus. This effect is dependent upon the way of addition to the Mg ions, and the extent of the 3H-dTTP incorporation is closely related to the concentration of the vesicles. A role of phospholipids on the activity of the DNA-related enzymes is suggested.
