SAMSON: a software package for the biopolymer primary structure analysis.

The SAMSON package is a tool for advanced analysis of primary DNA, RNA and protein structures. The package consists of 16 programs performing statistical analysis and comparison of biopolymer sequences, search for homologies, translation of DNA and RNA sequences into amino acid sequences, splicing of RNA sequences and restriction map construction, recognition of functionally related sites in biopolymer molecules, textual analysis of DNA and RNA regulatory sites and prediction of intermolecular hybridization sites in DNA and RNA molecules.

[The computer program package "SAMSON" for analysis of primary structure of biopolymers].

A program package "SAMSON" for the computer analysis of biopolymer primary structures is described. All possible modes of sequence investigation are considered. The programs for sequence comparison are described in some details. The general principles of a program package organisation and of its user interface are also mentioned. For more complete information see Vernoslov S.E. et al. "Program package "SAMSON" for the analysis of the polymer primary structures", parts 1 and 2, Poustchino, ONTI NCBI, 1989.

[Study of the structure of metal-binding centers of calmodulin by EXAFS-spectroscopy].

An investigation of Ca2+-binding centers of calmodulin was carried out by EXAFS-spectroscopy. The experimental results for protein preparations of calmodulin in which Ca2+ was isomorphically replaced by Tb3+ were obtained by a spectrometer working at the Institute of Nuclear Physics. For spectra analyses a standard method of Fourier transformation was used. Coincidence main maxima on phi (r) curves and identity of Fourier transformation for calmodulin and parvalbumin in the 2-6 A interval allow to infer the identity of Ca2+-binding centers of calmodulin and parvalbumin.

[Study of Ca2+-binding centers of parvalbumin by the distant fine structure of x-ray absorption spectra].

An investigation of Ca2+-binding centers of parvalbumin II and III by analysing distant fine structure of X-ray absorption spectra of metal was performed. Protein preparations of parvalbumin II and III in which Ca2+ was isomorphically replaced by Tb3+ were studied. For spectra analyses a standard method of Fourier transformation was used. The middle of the first absorption maximum was taken as origin for energy calculations. Comparison of spectra and modules of Fourier transformations for normalized oscillations of the X-ray spectra of absorption of the II and III components, revealed that the spectra and Fourier-transformants coincide in the 2--6 A interval. This allows to infer the coincidence of the coordinate numbers, average interatomic distances and their dispersions in Ca2+-binding centers of the two protein components.
