(activators). The GTFs combine with RNA polymerase to form a preinitiation complex that is competent to initiate transcription. Although the general transcription factors can support only a basal level of transcription in the absence of activators, the preinitiation complex is the most import...
The predicted structures of the unique MT-5J type Mn4Ca clusters (the most stable tautomer in each Si-state; i = 1–3) revealed that two substrate water molecules on the terminal Mn ion are bound in such a way as completely consistent with the S-state dependence of observed fast and ...
Chemistry of ion coordination and hydration revealed by a K+ channel-Fab complex at 2.0 Å resolution Zhou Y, Morais-Cabral JH, Kaufman A, MacKinnon R (2001) Chemistry of ion coordination and hydration revealed by a K+ channel-Fab complex at 2.0 A resolution. Nature 414(6859): 43-48....
When handling metallic centers of higher coordination numbers, one is commonly deluded with the presumption that any assembled metal complex geometry (including a crystallographic one) is good enough as a starting structure for computational chemistry ca
(EDX) confirmed that Zr content follows the stoichiometric ratio. Particle size decreases with increasing doping concentration. Increasing Zr content enhances optical transmittance in the visible range; a 9 wt% doping level produced the highest average optical transmittance at 69%. An empirical law ...
To assess the interaction between the protein and the ligand within the predicted complex structure, we determine the extent of intermolecular native contact formation. We adopt a definition similar to that of the Local Distance Difference Test (LDDT) score, previously employed for quantifying the nat...
of suspended elements from the soils and rock mineral of their basins. This assembly specifies the successive mechanism which affects groundwater chemistry as rock dominance. The last mechanism is consisting of evaporation–fractional definition. This process produces an order of series extending from ...
Native protein structure is often regarded as a prerequisite for biological function, by epitope-specific interactions and molecular fitness for a finite number of cellular targets. Yet, a lack of structural definition may, in some cases, result in a gain of function, in part by uncovering ...
existence is predicted in literature50,51. The signal in Fig.1ecould correspond to either a fused or intertwined knot. In line with the previous definition, we represent factored composite knots as\(\left\langle {n_1-\overline {k_1}-n_2-\overline {k_2}-n_3 \ldots-\overline {k_i...
Complex Ion Definition:Complex ions areionswith a centralmetalion bonded to one or moremoleculesor ions. They are a type of coordination complex. The central ion is the coordination center, while the molecules or ions bound to it are termed complexing agents or ligands. Examples:The copper ammin...
