A dodecavanadate, [V₁₂O₃₂]⁴¯, is an inorganic bowl-type host with a cavity entrance with a diameter of 4.4 Å in the optimized structure. The linear, bent, and trigonal planar anions, are tested as a guest anion and the formation of host-guest complexes, [V₁₂O₃₂(X)]⁵¯ (X = CN¯, OCN¯, NO₂¯, NO₃¯, HCO₂¯, and CH₃CO₂¯) were confirmed by X-ray crystallographic analyses and ⁵¹V NMR study. The degree of the distortion of the bowl from a regular bowl to an oval bowl depends on the shape of the guest anion, after host-guest complex formation. In ⁵¹V NMR spectroscopy, all the chemical shifts of the host-guest complexes are clearly shifted after the guest incorporation. The incorporation reaction rates for OCN¯, NO₂¯, HCO₂¯, and CH₃CO₂¯ are much larger than those of NO₃¯ and halides. The incorporated non-spherical molecular anions in the dodecavanadate host are easily dissociated or exchanged to other anions, while the spherical halides in the dodecavanadate host are preserved without dissociation even in the presence of the tested anions.

Borinic acids have typically not been considered as hydrogen bond donor groups in molecular recognition. Here, we describe a bifunctional borane / borinic acid derivative (2) in which the two function...
Evidence for a shape-based recognition of odorants in vivo in the human nose from an analysis of the molecular mechanism of lily-of-the-valley odorants detection in the Lilial and Bourgeonal family using the C/Si/Ge/Sn switch strategy.
We performed an analysis of possible mechanisms of ligand recognition in the human nose. The analysis is based on in vivo odor threshold determination and in vitro Ca2+ imaging assays with a C/Si/Ge/S...
Most of the halogen bonding receptors for anions described use halogen bonding binding sites solely in the anion recognition process; only a few examples report the study of anion receptors in which t...

Protein motif that contains a 33-amino acid long sequence that often occurs in tandem arrays. This repeating sequence of 33-amino acids was discovered in ANKYRIN where it is involved in interaction with the anion exchanger (ANION EXCHANGE PROTEIN 1, ERYTHROCYTE). Ankyrin repeats cooperatively fold into domains that mediate molecular recognition via protein-protein interactions.
Measurement of the polarization of fluorescent light from solutions or microscopic specimens. It is used to provide information concerning molecular size, shape, and conformation, molecular anisotropy, electronic energy transfer, molecular interaction, including dye and coenzyme binding, and the antigen-antibody reaction.
Models used experimentally or theoretically to study molecular shape, electronic properties, or interactions; includes analogous molecules, computer-generated graphics, and mechanical structures.
A multiprotein complex composed of the products of c-jun and c-fos proto-oncogenes. These proteins must dimerize in order to bind to the AP-1 recognition site, also known as the TPA-responsive element (TRE). AP-1 controls both basal and inducible transcription of several genes.
