Studies of the Interaction of LCAT with Lipoprotein Substrates in HDL Deficient Plasma Systems

Description: Enzymatic and lipid transfer reactions involved in reverse cholesterol transport were studied in HDL deficient plasma systems. Fasting plasma samples were obtained from control and cholesterol fed guinea pigs as well as from a fish eye disease patient and were used to localize the enzyme LCAT among plasma lipoproteins (VLDL, LDL, and HDL). In both guinea pig and fish eye disease patient plasma, the LCAT activity was found in association with the HDL type particles. Cholesterol feeding in guinea… more

Characterization of Human Glucose-6-Phosphate Isomerase of Different Sizes

Description: Glucose phosphate isomerase (GPI) was purified from human placenta utilizing cross-linked spherical particle phosphocellulose. In three steps, GPI could be purified approximately 5500 fold with greater than 50% recovery. The purified enzyme exhibited four bands upon non-denaturing PAGE and isoelectric focusing (IEF) when stained with GPI specific activity stain. The four isozymes were isolated by preparative IEF. The isoelectric points of the isozymes were determined. Sodium dodecyl sulfate (SD… more

Physical Mapping of Human Transfer RNA Gene Clusters

Description: Two plaque-pure phage lambda clones designated as λhtX-l and λhtX-2 that hybridized to unfractionated bovine liver tRNA were isolated from a human X chromosome-specific library. The λDNAs were characterized by restriction mapping and Southern blot hybridization techniques. The human DNA segment in λhtX-l contains five or more presumptive tRNA genes and at least one Alu family member. The 19-kilobase human DNA insert in λhtX-2 contains two or more presumptive tRNA genes and at least three Alu fa… more
