[Ag(P4)2][Al((F3C)CO2)4], with the tetrahedral P4 mol. as ligand, was prepd. and its crystal structure and Raman spectra detd. The Ag coordination is nearly planar and the calcd. mol. orbitals of the cation indicate the electronic basis for this geometry. ...
We present here the structure of Yer0l0c protein of unknown function, solved by Multiple Anomalous Diffraction and revealing a common fold and oligomerization state with proteins of the regulator of ribonuclease activity A (RraA) family. In Escherichia col ...
The ligand N,N'-bis[6-carboxy-2-pyridylmethyl]ethylenediamine-N,N'-diacetic acid (H4bpeda) was synthesized using an improved procedure which requires a reduced no. of steps and leads to a higher yield with respect to the published procedure. It was obtaine ...
The reactions of [Fe2(CO)9] with 2-exo,3-exo-bis(chloromethyl)-5,6-di(methylidene)-7-oxabicyclo[2.2.1]hep tane (5) and with 5,6-di(methylidene)-7-oxabicyclo[2.2.1]heptane-2-exo,3-exo-dimethyl bis(methanesulfonate) (6) afforded, together with the correspond ...
The determination of the crystal structure of the bacterial protein proaerolysin provided the first view of a pore-forming toxin constructed mainly from beta-sheet. The structure that was obtained and subsequent crystallographic and biochemical studies hav ...
The extracellular interferon gamma receptor alpha-chain (IFN gamma R) is believed to comprise two discrete approximately 110 amino acid immunoglobulin-like domains, perhaps similar to those seen in the crystal structure of the extracellular human growth ho ...
The structural prototype of a new generation of regioselectively addressable functionalized templates (RAFTs) for use in protein de novo design has been synthesized and crystallized. The structure of the aromatically substituted cyclodecapeptide was determ ...
The crystal structure of the new synthetic compound Ba-5[B20O33(OH)(4)] . H2O was established by the methods of X-ray diffraction (a Stoe IPDS diffractometer, lambda MoKalpha, 1860 independent reflections, anisotropic refinement, R = 1.95%, localization of ...
Multiplets in two-dimensional correlation spectra are encoded in a manner that depends on the topol. of the coupling network but not on the values of the coupling consts. Comparison of exptl. multiplets with a data bank contg. some 10,000 possible patterns ...
The three-dimensionally modulated incommensurate crystal structure of lazurite from the Baikal region was determined for the first time. The structure was solved within the cubic system with the unit-cell parameter a(cub) = 9.077(1) Angstrom and the (3+2)- ...
