现在我们看Ramachandran图上的最后一个区域。一部分氨基酸残基、并不是所有的氨基酸残基的phi和psi二面角值可以允许落在这个区域。这个区域对应的是loop环结构。但要注意的一点是,形成loop环的氨基酸残基可以是任何允许的phi和psi二面角值。因此在Ramachandran图的三个区域都会存在形成loop环的残基。所以,要得到一个α螺旋,...

omega. -phi-psi current-mixing angles and mass formulas from SU(4) spectral-function sum rules. [Electron-pair partial widths] Spectral-function sum rules for broken SU(4) symmetry are used to obtain the current-mixing angles for the vector mesons ..omega.., phi, and psi (3095) and.....
In our experience, the Ramachandran plot is one of the simplest and most sensitive means for assessing the quality of a protein model in the absence of experimental data. The major reason for this is probably the fact that the φ, ψ angles (or combinations of these) are not usually ...

The NMR 3D structure of CytC (PDB entry 2MLW) was determined using NOE distances, dihedral angles and hydrogen bonds (Table 1). As a member of the Cyt protein family, CytC has a cytolysin fold, i.e. a single domain of a/b architecture consisting of a b-sheet surrounded by two a-...
Studies of angular and time distributions and CP-violating observables in$B_so J/\psi \phi$ decays yield a space of parameters which can beconsiderably reduced if relative strong phases among different amplitudes arespecified. We show that the relations between $B_s o J/\psi \phi$ and ...
