   <abstract xml:lang="ru">
    <p>Факторы транскрипции TnrA и GlnR , представители семейства MerR регуляторов транскрипции, у бактерий Bacillus subtilis контролирует гены белков азотного метаболизма в условиях недостатка и избытка азота в среде. Одним из механизмов регуляции их ДНК-связывающей активности является взаимодействие с глутаминсинтетазой. Методом поверхностного плазмонного резонанса установлено, что глутаминсинтетаза оказывает различное действие на активность этих факторов транскрипции. В присутствии ингибированной глутаминсинетазы ДНК-связывающая активность белка TnrA снижается, тогда как аффинность GlnR к ДНК возрастает. Этот факт коррелирует с активностью факторов TnrA и GlnR в различных условиях доступности азота и характеризует глутаминсинтетазу как триггерный фермент, контролирующий азотный обмен клетки. </p>

   <trans-abstract xml:lang="en">
    <p>The transcription factors TnrA and GlnR, members of the MerR family of transcription regulators, control the genes of the nitrogen metabolism in Bacillus subtilis under conditions of nitrogen deficiency and excess, respectively. Their DNA-binding activity is regulated by the interaction with the glutamine synthetase, the key enzyme of ammonium assimilation. By surface plasmon resonance it has been established that glutamine synthetase has a different effect on the activity of these transcription factors. In the presence of inhibited glutamine synthetase, the DNA-binding activity of TnrA is decreased, while GlnR affinity to DNA increases. This fact correlates with the activity of TnrA and GlnR in various conditions of nitrogen availability and characterizes the glutamine synthetase as a trigger enzyme that controls nitrogen metabolism.</p>
