Ternary structures

Binary and ternary structure types with isolated B atoms are listed in Table 1. In the metal borides of the formula (My, Mi ),B or T,(B, E) (M-p, M - = transition metals, E = nonmetal), the influence of the radius ratio as well as the...

Several other considerations and applications of the space-filling concept can be found in Parthe (1961), for instance space-filling diagrams of ternary structures, applications of space-filling concept for discussing and predicting possible pressure structures, etc. 

Figure 7.6. Examples of binary and ternary structures which may be described in terms of combination of fragments of the W and A1B2 types (adapted from Rogl 1992).

DNA-TopI-rebeccamycin crystal ternary structure has proven the mechanism of action, showed binding specificity with enzyme, with maleimido and the sugar moiety affinity for interacting with the topi enzyme, while the indolocarbazole moiety intercalates into the DNA base pairs to form covalent interactions [16],... 

A mechanism for explaining how oligomeric and polymeric forms of a protein or polypeptide can arise by three-dimensional swapping of internal domains in monomers. The basic idea is that a protein s ternary structure is stabilized by the contacts between its domains, and under certain circumstances, the domains of several polypeptide chains may bind in a way that gives rise to nonphysiologic oligomers, polymers, and aggregates. 

There are indications that the rates of degradation depend on the thermostabihty and oxidation of proteins, findings that suggest that the integrity of protein ternary structure may in part determine the overall intracellular... 

Changes in the protein ternary structure during adsorption. There is a difference in softness between different proteins and the ternary structure may change when it adsorbs. 

We just solved the ternary structure of PGK from Trypanosoma brucei in complex with ADP and 3-phosphoglycerate. The enzyme is in the closed conformation that has eluded crystallographers for 20 years.

The crystal structure of the cyclophilin-CsA-calcineurin ternary structure has yet to be resolved but the ternary structure formed by rapamycin-mediated interactions between FKBP12 and the 12-kDa fKBP-rapamycin binding (FRB) domain of the 289-kDa FRAP protein has been determined with 2.7 A resolution (Choi et al, 1996), which has more recently been refined to 2.2 A resolution (Liang et al, 1999). The structure of this complex is shown in Fig. 6 (see color insert). Several similarities as well as differences in the overall mode of interaction can be seen relative to what is observed with the FKBP-FK506-cal-cineurin structure. As was seen with the FKBP-FK506 calcineurin ternary complex, there are no overall gross conformational changes... 

Ternary structure Such structures are ones with three elements present (e.g CaC03, CaTi03). The two possible fundamentally different features of such compounds are... 

One ubiquitous ternary structure is that of PbFCl (ZrSiS, BiOCl, Co2Sb, Fe2As).16,71 We ll call it MAB here because in the phases of interest to us the first element is often a transition metal and the other components, A and B, are often main group elements. Diagram 91 shows one view of this structure, 92 another. 

Low dimensionality characterizes another set of MS2 sublattices, now in ternary structures of the type of KFeS2 or Na Fe2S4.93,94 In these molecules one finds one-dimensional MS2 chains, consisting of edge-sharing tetrahe-dra, 134. 

ECD domains of hGHR and PRLR and have consequential effects on the ternary structure of their respective complexes (see later) (Somers et al, 1994). 

I) Ordered substitutions of atoms carrying identical charges. This kind of substitution is observed in the formation of ternary structures from the corresponding binary parents. For example, the crystal structure of the ternary Y6Pb2Sen can be derived from the binary TmgSu parent by the substitution of Tm by Pb (Figure 111).
