A potential function for protein folding
(Kluwer Academic Publishers; J. C. Baltzer AG, Scientific Publishing Company ; Springer Science+Business Media, 1991-12)
One of the most difficult problems in computational chemistry is the prediction of the three-dimensional structure of a protein molecule given only its amino acid sequence. Although there are several programs for calculating ...
Modulation of Na+/alanine cotransport in liver sinusoidal membrane vesicles by internal divalent cations
(Elsevier, 1990-04-30)
Rat liver basolateral plasma membrane (bILPM) vesicles resuspended in 5 mM Mg2+-, Ca2+-, Mn2+- or Co2+-containing media exhibited a markedly lower rate of Na+-stimulated -alanine transport. Divalent cation inhibition of ...
A new preparation of highly functionaized aromatic and heteroaromatic zinc and copper organometallics
(Elsevier, 1990)
Functionalized aromatic iodides possessing an ester, cyano, chloride or keto group can be converted to arylzinc iodides by reaction with zinc in DMF or DMAC. After transmetallation to the corresponding arylcopper, they ...
Thermodynamics of ammonium halopallidates I. Heat capacity and thermodynamic properties of (NH4)2PdCl6 at temperatures from 6 K to 350 K
(Elsevier, 1992-09)
The heat capacity of ammonium hexachloropallidate (NH4)2PdCl6 was measured at temperatures from 6 K to 350 K by adiabatic calorimetry. The heat-capacity curve is smooth and without anomalies. It rises rapidly from T0 to T ...
Incubation in cyclohexene decomposition at high temperatures
(John Wiley & Sons, Inc., 1990-02)
A detailed master equation simulation has been carried out for the thermal unimolecular decomposition of C 6 H 10 in a shock tube. At the highest temperatures studied experimentally [J. H. Kiefer and J. N. Shah, J. Phys. ...
SN2' Substitutions of 1,3-Dichloropropenes with the Functionalized Copper-Zinc Reagents RCu(CN)ZnX
(Elsevier, 1990)
The addition of benzenesulfenyl (or benzeneselenyl) chlorides to propargylic chlorides affords regio- and stereospecifically (E)-1,3-dichloro-2-phenylsulfenyl (or phenylselenyl) propenes (2a-c). These new reagents were ...
Isolation and purification of a squamous cell carcinoma of the head and neck-associated antigen identified by autologous antibody
(Elsevier, 1993-04-30)
We have previously shown that detection of autologous antibody activity to squamous cell carninoma of the head and neck many be augmented by dissociation in immune complexes. Western blot analysis with autologous antibody ...
Identity and some properties of the -threonine aldolase activity manifested by pure 2-amino-3-ketobutyrate ligase of Escherichia coli
(Elsevier, 1993-08-07)
2-Amino-3-ketobutyrate ligase catalyzes the reversible, pyridoxal 5'-phosphate-dependent condensation of glycine with acetyl CoA forming the unstable intermediate, 2-amino-3-ketobutyrate. Several independent lines of ...
Heat capacity of deuterated ammonium tetrafluoroborate ND4BF4 from 7 K to 348 K
(Elsevier, 1990-10)
The heat capacity of deuterated ammonium tetrafluoroborate ND4BF4 was measured from 7 K to 348 K by adiabatic calorimetry. The curve for heat capacity against temperature is smooth with a broad maximum between 120 K and ...
