abstract

  • Apolipoprotein C-I, a protein constituent of the very low density lipoproteins of human plasma, consists of a single chain of 57 amino acids. The total synthesis of a protein corresponding to apolipoprotein C-I in physical properties and compositions was accomplished by solid phase techniques employing a modified polystrene incorporating spacer groups between the point of attachment of the first residue and the polymer matrix. The synthetic apoprotein was shown to activate lecithin:cholesterol acyltransferase to the same extent as the native protein. Comparative lipid-binding studies with dimyristoyl phosphatidylcholine gave complexes for native and synthetic apoprotein which floated at the same density after ultracentrifugation in KBr gradients and had virtually the same lipid:protein ratios.
