The development of ideas on the mechanism of this process (the signal hypothesis, the loop model, etc.) is followed. The differences between prokaryotes and eukaryotes with respect to protein transport are discussed. Data for the involvement of biol. membranes in protein translocation are presented. The contribution of some new genetic approaches to the study of this process is summarized and the perspectives of using these methods to solve important theor. and practical problems (particularly for biotechnol.) are outlined.Item Studies on the ultrastructure of Yersinia pseudotuberculosis after treatment with some detergents and solvents(Gustav Fischer Verlag, Stuttgart, 1977) Cherepova, Nadja; Baykousheva, Svetla; Veljanov, DThe ultrastructural changes in 3 strains Yersinia pseudotuberculosis with different virulence after treatment with sodium lauryl sulfate (SLS) and petroleum ether were studied. The ultrafine sections after treatment with SLS show heavy destructive changes, concerning the cell wall, the cytoplasmic membrane and the inner structure of the cell. It was established that the same cells Y. pseudotuberculosis after cultivation on a medium with glycerol show a tendency to recover their ultrastructure. The cells treated with petroleum ether did not exhibit any notable ultrastructural changes.Item Metabolism of [1-14C]linoleic acid in human promyelocytic leukemia HL-60 cells grown and differentiated in serum-free medium(1993) Baykousheva, SvetlaThe metabolism of [1-14C]linoleic acid (LA) was studied in human promyelocytic leukemia cell line HL-60, grown and differentiated in serum-free medium. Both undifferentiated and dibutyryl cAMP-differentiated HL-60 cells exhibited similar patterns of conversion of LA to 4 other major fatty acids (i.e., 18:3, 20:3, 20:4, and 22:4).Item The role played by β-oxidation in unsaturated fatty acid biosynthesis(1994) Sprecher, Howard; Baykousheva, SvetlaThe authors hypothesized that a role for peroxisomes might be to chain shorten fatty acids but that the products would be transported to the endoplasmic reticulum where they would be esterified into lipids. Results showed that when microsomes and 1-acyl-sn-glycero-3-phosphocholine are added to peroxisomes that competing reactions take place, i.e. β-oxidn. and esterification.
