Claims (7)
1. Штамм Escherichia coli, содержащий оба гена, tdcBC и pckA, которые инактивированы.
2. Штамм Escherichia coli по п.1, в котором pckA-ген инактивируют путем встраивания фрагмента чужеродного pckA-гена, содержащего устойчивый к антибиотику ген, имеющий сайт связывания сайт-специфической рекомбиназы на каждом его конце в родительском штамме Escherichia coli, содержащем ассоциированный с деградацией L-треонина оперон tdcBC, который инактивирован, а затем гомологической рекомбинации между фрагментом чужеродного pckA-гена и pckA-геном на хромосоме для инактивации хромосомного pckA-гена.
3. Штамм Escherichia coli по п.2, в котором pckA-ген инактивируют путем удаления встроенного в него устойчивого к антибиотику гена в результате активности сайт-специфической рекомбиназы, экспрессируемой в штамме Escherichia coli, и наличия одной копии связывающего сайта сайт-специфической рекомбиназы в хромосомном pckA-гене.
4. Штамм Escherichia coli по п.2, в котором сайт-специфическая рекомбиназа представляет собой FLP, Cre или XerC/D.
5. Штамм Escherichia coli по п.2, представляющий собой Escherichia coli FTR2717 (KCCM-10475), содержащий на хромосоме pckA-ген, инактивируемый путем введения фрагмента чужеродного pckA-гена, содержащего устойчивый к антибиотику ген, имеющий loxP-сайт на каждом его конце в родительском штамме Escherichia coli, содержащем ассоциированный с деградацией L-треонина tdcBC-оперон, который инактивирован.
6. Способ получения L-треонина с использованием штамма Escherichia coli по любому из пп.1-5.
7. Рекомбинантная плазмида pT7ΔpckA::loxpcat, содержащая фрагмент pckA-гена, содержащий устойчивый к хлорамфениколу ген и loxP-сайты, где указанную рекомбинантную плазмиду получают путем клонирования неполного pckA-гена в pT7Blue-вектор, с образованием pT7Blue/pckA-плазмиды, получая из ploxpcat2-плазмиды ДНК-фрагмент, содержащий устойчивый к хлорамфениколу ген и loxP-сайты, loxpcat2, и лигируя loxpcat-ДНК-фрагмент с NruI-обработанной pT7Blue/pckA-плазмидой.
