Structure of N-terminal Domain of NPC1 Reveals Distinct Subdomains for Binding and Transfer of Cholesterol
2009-06-26

SUMMARYLDL delivers cholesterol to lysosomes by receptor-mediated endocytosis. Exit of cholesterol from lysosomes requires two proteins, membrane-bound Niemann-Pick C1 (NPC1) and soluble NPC2. NPC2 binds cholesterol with its isooctyl side chain buried and its 3�-hydroxyl exposed. Here, we describe high-resolution structures of the N-terminal domain (NTD) of NPC1 and ...

Structure of N-Terminal Domain of NPC1 Reveals Distinct Subdomains for Binding and Transfer of Cholesterol

LDL delivers cholesterol to lysosomes by receptor-mediated endocytosis. Exit of cholesterol from lysosomes requires two proteins, membrane-bound Niemann-Pick C1 (NPC1) and soluble NPC2. NPC2 binds cholesterol with its isooctyl side chain buried and its 3{beta}-hydroxyl exposed. Here, we describe high-resolution structures of the N-terminal domain (NTD) of NPC1 and complexes ...

Differentiation of two mouse cell lines is associated with hypomethylation of their genomes.
1984-09-01

Methyl-accepting assays and a sensitive method for labeling specific CpG sites have been used to show that the DNA of F9 embryonal carcinoma cells decreases in 5-methylcytosine content by ca. 9% during retinoic acid-induced differentiation, whereas the DNA of dimethyl sulfoxide-induced Friend murine erythroleukemia (MEL) cells loses ca. 3.8% of its methyl groups. These values ...

Proton-transfer reactions on hexanuclear platinum clusters: reversible heterolytic cleavage of H2 and C-H activation affording a linear, cluster-containing polymer.
2010-08-16

The hexanuclear cluster {Pt(6)}H(2) (2) contains a sterically hindered and chemically stable {Pt(6)} = Pt(6)(mu-PtBu(2))(4)(CO)(4) core, with the six metals forming an edge-bridged tetrahedron. The two hydrides are the reactive sites of the cluster and lie on opposite sides of the cluster, terminally bonded to the two "apical" edge-bridging platinum centres. Indeed, cluster 2 ...

Dual Effects on Choice of Conditioned Reinforcement Frequency and Conditioned Reinforcement Value
2010-03-01

Pigeons were presented with a concurrent-chains schedule in which the total time to primary reinforcement was equated for the two alternatives (VI 30 s VI 60 s vs. VI 60 s VI 30 s). In one set of conditions, the terminal links were signaled by the same stimulus, and in another set of conditions they were signaled by different stimuli. Choice was in favor of the shorter ...

Properties of Succinyl-Coenzyme A:l-Malate Coenzyme A Transferase and Its Role in the Autotrophic 3-Hydroxypropionate Cycle of Chloroflexus aurantiacus
2006-04-01

The 3-hydroxypropionate cycle has been proposed to operate as the autotrophic CO2 fixation pathway in the phototrophic bacterium Chloroflexus aurantiacus. In this pathway, acetyl coenzyme A (acetyl-CoA) and two bicarbonate molecules are converted to malate. Acetyl-CoA is regenerated from malyl-CoA by l-malyl-CoA lyase. The enzyme forming malyl-CoA, succinyl-CoA:l-malate ...

Immunologic and proteolytic analysis of HIV-1 reverse transcriptase structure.
1990-04-01

HIV-1 virions contain two reverse transcriptase polypeptides that have apparent molecular weights of 66 and 51 kDa. The 51-kDa form lacks the carboxy-terminal sequences found in the 66-kDa form, and is believed to be a proteolytic digestion product. We have treated purified 66-kDa reverse transcriptase with viral and nonviral ...
