What's the difference between tetrahedral and tetrahedrally?
Tetrahedral
Definition:
(a.) Having, or composed of, four sides.
(a.) Having the form of the regular tetrahedron.
(a.) Pertaining or related to a tetrahedron, or to the system of hemihedral forms to which the tetrahedron belongs.
Example Sentences:
(1) The results suggest that the transition state contains a tetrahedral carbon with the R configuration as a result of the direct attack of an oxygen nucleophile at C-6 of AMP.
(2) The distribution of angles between two hydrogen bonds at a single water molecule, as defined by the three nonhydrogen atoms involved, was centered near the tetrahedral angle.
(3) Theoretical conformational analysis of the tetrahedral complexes of trypsin with the N-acetyl-L-lysine methyl amide, which are formed at the acylation and the deacylation stages of the catalytical act has been carried out.
(4) Furthermore, zinc binding to one of the mutant finger proteins suggests either that only a precise finger structure formed by the tetrahedral coordination of zinc to the four consensus ligands is required for trans-activation or, possibly, that one of several neighboring histidine residues in various combinations with three of the consensus cysteine residues normally coordinates zinc.
(5) While the spectroscopic properties indicate an exclusively tetrahedral type of metal-thiolate sulfur coordination for the binding of the first six metal ions, they suggest that the seventh metal ion is coordinated in a different fashion.
(6) Circular dichroic (CD) and magnetic CD spectra indicate that the first Co2+ binding site is tetrahedral-like and that the second is octahedral-like.
(7) The perchlorate ion just fails to have regular tetrahedral geometry within the experimental error, and has an average Cl-O bond length of 1.433 (6) A.
(8) The Co(II) protein shows a set of d-d absorption bands typical of a tetrahedral Co(II) complex at 695 (epsilon = 565 M-1 cm-1), 642 (epsilon = 655 M-1 cm-1), and 615 nm (epsilon = 510 M-1 cm-1) and two intense bands at 349 (epsilon = 2460 M-1 cm-1) and 314 nm (epsilon = 4240 M-1 cm-1) typical of Co(II)----(-)S- charge transfer.
(9) The glycol moiety in this novel acid, dihydroxyethylene isostere, is suggested to act as a transition-state analogue and mimics the tetrahedral intermediate formed during the enzyme-catalyzed hydrolysis of the peptidic bond.
(10) Moreover, a considerable deviation from a spherical or tetrahedrally symmetric structure of alpha-crystallin is inferred.
(11) A protein is represented by a self-avoiding path of connected vertices on a tetrahedral lattice, with several amino acid residues assigned to each lattice vertex.
(12) The ion is co-ordinated by three histidine residues, 26, 81 and 167, and one aspartic acid residue, 173, in a tetrahedral arrangement strongly distorted towards trigonal pyramidal.
(13) We now report the rates of formation of enzyme-inhibitor complexes of two types, those which do and those which do not form such tetrahedral intermediates.
(14) The phase has been characterised as a phosphorus deficient dahllite variant of apatite in which the crystal structure has been weakened by the incorporation of water molecules and tetrahedral hydroxyl groups in isomorphic substitution conforming with the McConnell-type defect.
(15) We have determined the effect of pH on the binding affinities of the conjugate bases of four different tetrahedral oxyacids to the sulfate-binding protein.
(16) This change in protein conformation both exposes a cryptic protein pocket on each subunit to which phenol binds and forces the HisB10 zinc sites to undergo a change in coordination geometry from octahedral to tetrahedral [Derewenda, U., Derewenda, Z., Dodson, E. J., Dodson, G. G., Reynolds, C. D., Smith, G. D., Sparks, C., & Swensen, D. (1989) Nature 338, 593-596].
(17) The boron atom is coordinated tetrahedrally, with one of the two additional boronic acid oxygen atoms lying in the "oxyanion hole" and the other at the leaving group site identified in previous studies (ROBERTUS, J.D., Kraut, J. ALDEN, R.A., and BIRKTOFT, J.J. (1972) Biochemistry 11, 4293-4303).
(18) The spectrum of the low-affinity site (A site) shows two absorption maxima at 505 nm and 586 nm with epsilon values of 170 M-1 cm-1 and 240 M-1 cm-1, respectively, which indicates a distorted tetrahedral or pentacoordinated complex structure as also observed for the enzyme from Streptomyces violaceoruber [Callens et al.
(19) The possibility of accumulating a tetrahedral intermediate during the papain-catalysed hydrolysis of Z-Lys-pNA is discussed.
(20) These observations are in accord with the view that the reaction involves enzyme-bound phosphorylated intermediates and provide evidence for a phosphorylated tetrahedral intermediate, whose formation is required for coupling.
