Abstrakt: It is assumed that unknown mechanisms can be involved in adaptation Mycoplasma gallisepticum to unfavorable factors, one of these can be local rearrangements of the structure and spatial organization of the chromosome. To study these mechanisms, we obtained a culture of M. gallisepticum with synchronized division and isolated the nucleoid fraction from this culture by the method of mild cell lysis and centrifugation in a sucrose gradient. Liquid chromatography-mass spectrometry analysis of the proteome showed that in comparison with the cell lysate, the nucleoid fraction was enriched with DNA-binding proteins. This analysis will help to find new nucleoid-associated proteins and to study their dynamics, distribution, and their role during infection and under stress conditions.
