A method and software tool to develop patterns of protein families has been designed. These patterns are intended for the identification of local similarities in arbitrary amino acid sequences with proteins of the SWISS-PROT bank. The method is based on the physical, chemical and structural properties of amino acids. It assembles a 'best set' of elements (a(More)
Using a chemically synthesised adapter, the coding part of an artificial gene for human leukocyte alpha 2 interferon (ifn-alpha 2) has been duplicated. The adapter contained a termination signal of the first gene (TAA) within the Shine-Dalgarno sequence of the second gene (TAAGGA), distance between the terminating codon and starting codon of the second gene(More)
The electrophoretic pattern of glucose-6-phosphate dehydrogenase (G6PD) was studied in 60 intergeneric fox hybrids (Alopex lagopus x Vulpes vulpes), 33 females and 27 males. It is shown that the structural gene for G6PD, designated Gpd, is located on the X chromosome in both Arctic and silver foxes. Analysis of G6PD patterns in the erythrocytes of hybrid(More)
Erythrocyte glucose-6-phosphate dehydrogenase (G6PD) was examined by 13% starch gel electrophoresis in 74 mules (42 females and 32 males), 35 donkeys, and ten horses. The quantitative expression of the parental alleles at the Gpd locus varies greatly in female mules from the hemizygous expression of the maternal allele to that of the paternal. The data(More)
A new computer method for detecting local structural regularities in genomes of different microorganisms is described. The method is based on the concepts of complexity and complexity profile of a finite sequence. The complexity measure taking into account the specificity of genetic texts (presence of repeats, symmetries, inversions) is proposed. The(More)
Based on the protein sequence data bank (PIR), the "variable fragment" bank, comprising pairs of closely related proteins, containing one or more strongly differing sites of primary structures was formed. The bank includes 465 "variable fragments" of 383 protein pairs. Amino acid residues composition of "variable fragments" was examined and indexes of(More)
