Oligopeptides in the formation of biological motivations
Neuroscience and Behavioral Physiology, 19871. Oligopeptides participate in the organization of eating and defense behavior and self-stimulation. 2. The majority of the investigated oligopeptides when injected into the lateral ventricles have an inhibitory influence on the manifestation of biological motivations.

Conformational Preferences of Proline Oligopeptides
The Journal of Physical Chemistry B, 2006A conformational study on the terminally blocked proline oligopeptides, Ac-(Pro)(n)()-NMe(2) (n = 2-5), is carried out using the ab initio Hartree-Fock level of theory with the self-consistent reaction field method in the gas phase and in solutions (chloroform, 1-propanol, and water) to explore the preference and transition between polyproline II (PPII)

Bacterial oligopeptide-binding proteins
Cellular and Molecular Life Sciences (CMLS), 2003This review focuses on bacterial oligopeptide-binding proteins, which form part of the oligopeptide transport system belonging to the ATP-binding cassette family of transporters. Depending on the bacterial species, these binding proteins (OppA) capture peptides ranging in size from 2 to 18 amino acids from the environment and pass them on to the other ...

Vibrational optical activity of oligopeptides
Biopolymers, 1995AbstractVibrational optical activity (VOA) is a relatively newspectroscopic technique, which has two principal manifestations, ir vibrational CD and vibrational Raman optical activity. Progress in the study of oligopeptides using both of these forms of VOA is reviewed from the perspective of theoretical and instrumental techniques, spectral results ...

Liposomalized Oligopeptides in Cancer Therapy
2005Organ-specific delivery of biofunctional agents is thought to enhance their activity and to reduce their side effects. Liposomes have been used as drug carriers in cancer chemotherapy, since they accumulate passively in tumor tissues due to an enhanced permeability and retention (EPR) effect. In addition, modification of liposomes with specific ligands

Oligopeptide signalling and the action of systemin
Plant Molecular Biology, 1999In the 19th century, the German botanist Julius von Sachs postulated the existence of chemical messengers that are responsible for the regulation of plant growth and development. The first such messenger was identified in the 1930s as indole-3-acetic acid, an auxin.

Biochemical problems of regulation by oligopeptides
Biochemistry (Moscow), 2004Some problems are considered which arise in biochemical studies on structure and function of natural oligopeptides consisting of 2-50 amino acid residues. The problems under consideration include the generation of oligopeptides from precursors, chemical structure, the role of functionally important radicals and spatial configuration, and structure ...
