Human very low density lipoprotein structure: interaction of the C apolipoproteins with apolipoprotein B-100.
Very low density lipoproteins (VLDL) are a heterogenous population of particles differing in size and composition. Heparin-Sepharose chromatography yields three VLDL subfractions. Two subfractions, VLDLNR-1 and VLDLNR-2, which are not retained by heparin, contain little or no detectable apolipoprotein (apo)E. According to negative stain electron microscopy, VLDLNR-1 is slightly larger than VLDL...
متن کاملStudies of a variant very-low-density lipoprotein with an acquired deficiency of apolipoprotein C-II.
1. A variant very-low-density lipoprotein was associated with severe hypertriglyceridaemia. Urea-polyacrylamide gel electrophoresis of the tetramethylurea-soluble apolipoproteins of these very-low-density lipoproteins (VLDL) showed that the apolipoprotein C-II content was less than 10% of that in VLDL from hypertriglyceridaemic (3-120 mmol/l) controls. 2. VLDL were incubated with bovine milk li...
متن کاملPreferential association of apolipoprotein E Leiden with very low density lipoproteins of human plasma.
Apolipoprotein (apo) E Leiden is a rare variant of human apoE characterized by defective receptor binding and associated with dominant transmission of type III hyperlipoproteinemia. In heterozygotes, apoE Leiden is present in higher concentrations in both total plasma and very low density lipoproteins (VLDL) than the other apoE allele product. In the present study we analyzed cell expression an...
متن کاملThe complete amino acid sequence of alanine apolipoprotein (apoC-3), and apolipoprotein from human plasma very low density lipoproteins.
The alanine apolipoprotein (apoLp-Ala) was isolated from patients with familial hyperlipoproteinemia (type V). ApoLpAla is a single chain protein of 79 amino acids with a single carbohydrate side chain containing 1 mole each of galactosamine and galactose, and 0 to 2 moles of sialic acid per mole of protein. The complete amino acid sequence of apoLp-Ala was determined by manual and automated Ed...
متن کاملStructure of apolipoprotein B-100 of human low density lipoproteins.
We have analyzed low density lipoproteins (LDL) apolipoprotein (apop) B structure by direct sequence analysis of LDL apo B-100 tryptic peptides. Native LDL were digested with trypsin, and the products were fractionated on a Sephadex G-50 column. The partially digested apo B-100 still associated with lipids was recovered in the void volume (designated trypsin-nonreleasable, TN, peptides). The re...
