In the presence of 4,4′-bipyridine, deprotoned L-valine chelates CuII ions into coordination layers which were linked into a framework by hydrogen-bonded chains resulting from nitrate anions and water molecules.BenyongFuzhouLouFuzhouXiaodong
OspD is a radical S-adenosyl-l-methionine (SAM) peptide epimerase that converts an isoleucine (Ile) and valine (Val) of the OspA substrate to d-amino acids... WG Walls,AL Vagstad,T Delridge,... - 《Journal of the American Chemical Society》 被引量: 0发表: 2024年 The Dr Ross Ingr...
Cells were designated as wild-type, A4V (mutant cells having SOD1 with alanine substituted to valine at position 4), and G93A (mutant cells having SOD1 with glycine substituted to alanine at position 93). These constructs were a gift from Dr. Lawrence J. Hay-ward (University of ...
Chemical speciation of binary complexes of Co(II), Ni(II) and Cu(II) with L-valine in 0.0-60.0% v/v acetonitrile-water mixtures was studied pH-metrically at an ionic strength of 0.16 mol L-1 at 303.0 K. The existence of different binary complexes was established from the modelling ...
The protonation constants of some α-amino acids (glycine (Gly), l -alanine (Ala), l -valine (Val), l -serine (Ser), l -leucine (Leu) and l -isoleucine (Ile)) were studied in water and DMSO–water solution mixtures containing 30, 50 and 70vol-% DMSO; in addition the complex ...
Chemical speciation of Co(II), Ni(II) and Cu(II) complexes of L-valine in 0.0-60.0% v/v propylene glycol-water mixtures at an ionic strength of 0.16 mol L-1 and 303.0 K was studied pH-metrically. Models containing different number of species were refined by using the computer pro...
Heat effects of mixing of aqueous solutions of Cu(NO 3 ) 2 and L-valine were measured by the calorimetric method at 298.15 K and a ionic strength of 0.5–1.5 (KNO 3 ). The standard heat effects of formation of the Cu(II) complexes with L-valine in an aqueous solution were obtained ...
