    Training of modern graduate takes place in the conditions of requirements of the Federal state educational standards aimed at development of students’ competences. In order to train a competent graduate, higher education institutions are looking for ways that will make this process more effective and dynamic. The purpose of the article is to analyze the experience of higher education institutions in the implementation of training in cooperation with the use of information technology. The wide development of information technologies and their penetration into various spheres of society has determined their implementation in the educational process. The use of information technology is based on the use of personal computers. Now this tool is an integral part of the modern educational process. Placing emphasis on the fact that learning in cooperation is not a fundamentally new technology the authors say that it acquires relevance by incorporating innovative technologies. The article considers the ideas of training in cooperation with the use of information technologies, raises the importance and significance of this issue in modern educational conditions. Training in cooperation expands the students' information field. On the basis of the study of scientific literature, the features of training in cooperation, its essence and value purpose for the formation of competence of students of pedagogical University are highlighted. The study suggests an increase in students ' motivation to study materials after the introduction of information technologies that allow them to be more mobile and creative. The process of mutual learning in the process of cooperation becomes more effective. The higher the motivation of the student to study the discipline is, the higher the level of his knowledge is. The results of the study can be used in the further implementation of information technologies for the development of the learning process in cooperation

    The Chemistry of Phospholipid Binding by the Saccharomyces cerevisiae Phosphatidylinositol Transfer Protein Sec14p as Determined by EPR Spectroscopy

    The major yeast phosphatidylinositol/phosphatidylcholine transfer protein Sec14p is the founding member of a large eukaryotic protein superfamily. Functional analyses indicate Sec14p integrates phospholipid metabolism with the membrane trafficking activity of yeast Golgi membranes. In this regard, the ability of Sec14p to rapidly exchange bound phospholipid with phospholipid monomers that reside in stable membrane bilayers is considered to be important for Sec14p function in cells. How Sec14p-like proteins bind phospholipids remains unclear. Herein, we describe the application of EPR spectroscopy to probe the local dynamics and the electrostatic microenvironment of phosphatidylcholine (PtdCho) bound by Sec14p in a soluble protein-PtdCho complex. We demonstrate that PtdCho movement within the Sec14p binding pocket is both anisotropic and highly restricted and that the C5 region of the sn-2 acyl chain of bound PtdCho is highly shielded from solvent, whereas the distal region of that same acyl chain is more accessible. Finally, high field EPR reports on a heterogeneous polarity profile experienced by a phospholipid bound to Sec14p. Taken together, the data suggest a headgroup-out orientation of Sec14p-bound PtdCho. The data further suggest that the Sec14p phospholipid binding pocket provides a polarity gradient that we propose is a primary thermodynamic factor that powers the ability of Sec14p to abstract a phospholipid from a membrane bilayer
