Thermolabile folding intermediates: inclusion body precursors and chaperonin substrates.
An unexpected aspect of the expression of cloned genes is the frequent failure of newly synthesized polypeptide chains to reach their native state, accumulating instead as insoluble inclusion bodies. Amyloid deposits represent a related state associated with a variety of human diseases. The critical folding intermediates at the juncture of productive folding and the off-pathway aggregation reac...
متن کاملSynthesis of heterobimetallic tungsten acetylacetonate / alkoxide complexes and their application as molecular precursors to metal tungstates
A series of M2W2(O)2(acac)2(OMe)10 [M = Co (1), Ni(2), Mg (3), Zn (4)] have been synthesised and structurally characterised by X-ray crystallography. All the compounds share common structural features which are identical to the analogous molybdenum species, with four edge-sharing octahedra situated in the same plane, and incorporating two 3-bridging and four 2-bridging methoxide groups. The d...
متن کاملHeterobimetallic peroxo-titanium(IV) nitrilotriacetate complexes as single source precursors for preparation of MTiO3 (M = Co, Ni and Zn).
Three isostructural heterobimetallic nitrilotriacetatoperoxotitanate complexes of general formula [M(H(2)O)(5)](2)[Ti(2)(O(2))(2)O(nta)(2)].7H(2)O [M = Co (1), Ni (2) and Zn (3)] have been isolated in pure crystals directly from the quaternary system of M(2+)-Ti(OC(4)H(9))(4)-H(2)O(2)-H(3)nta (H(3)nta = nitrilotriacetic acid) at pH = 4.0 and have been characterized by elemental analyses, IR, th...
متن کاملLariat RNA's as intermediates and products in the splicing of messenger RNA precursors.
The splicing of messenger RNA precursors in vitro proceeds through an intermediate that has the 5' end of the intervening sequence joined to a site near the 3' splice site. This lariat structure, which has been characterized for an adenovirus 2 major late transcript, has a branch point, with 2'-5' and 3'-5' phosphodiester bonds emanating from a single adenosine residue. The excised intervening ...
متن کاملRadical intermediates in the addition of OH to propene: photolytic precursors and angular momentum effects.
We investigate the photolytic production of two radical intermediates in the reaction of OH with propene, one from addition of the hydroxyl radical to the terminal carbon and the other from addition to the center carbon. In a collision-free environment, we photodissociate a mixture of 1-bromo-2-propanol and 2-bromo-1-propanol at 193 nm to produce these radical intermediates. The data show two p...
