[Funtional study of gene relA in the expression of amino acid operons. III. The effect of the allelic state of gene relA on the derepression of the threonine and isoleucine-valine operons of Escherichia coli K-12]

Autor: G G, Zaigraeva, R S, Shakulov, M M, Gusiatiner, V A, Livshits, N I, Zhdanova

Publikováno v: Genetika. 16(2)

During the derepression of threonine and isoleucine-valine operons the increase of activity of homoserine dehydrogenase and threonine deaminase respectively occurs only in relA+ strains of Escherichia coli K-12, while the activity of these enzymes in

[Gene relA function in the expression of amino acid operons. I. Effect of the allelic state of gene relA on phenotypic manifestations of auxotrophic threonine and isoleucine mutations in Escherichia coli K-12]

Autor: V A, Livshits, R S, Shakulov, G G, Zaigraeva, M M, Gusiatiner, N I, Zhdanova

Publikováno v: Genetika. 14(6)

The substitution of the relA gene mutant allele with wild type allele of this gene in strictly auxotrophic strain of Escherichia coli K-12 GT25, carrying thr B1007 mitation, results in the appearance of the partial dependence of the bacterial growth

[Inhibitory analysis of the respiration of bacteroids from the nodules of yellow lupine]

Autor: M V, Raĭkhinshteĭn, S S, Melik-Sarkisian, G G, Zaigraeva, V L, Kretovich

Publikováno v: Mikrobiologiia. 45(2)

Oxygen uptake and reduction of C2H2 by bacteroids was found to be inhibited by low concentrations of cyanide and azide. However, oxygen uptake was not completely suppressed even by 10(-3) M KCN. Cyanide-resistant respiration was not inhibited by sali

[Gene relA function in the expression of amino acid operons. II. Effect of the allelic state of gene relA on the overproduction of threonine by an Escherichia coli K-12 mutant resistant to beta-hydroxynorvaline]

Autor: M M, Gusiatiner, N I, Zhdanova, V A, Livshits, G G, Zaigraeva, R S, Shakulov

Publikováno v: Genetika. 14(6)

Mutants, resistant to threonine analogue, DL-alpha-amino-beta-hydroxyvaleric acid, were obtained after the treatment of Escherichia coli K-12 RelA- cells with nitrosoguanidine, and among them the strain with maximal threonine production (about 3g/l)

[Partial suppression of the effect of gene re1A in Fusr-mutant Escherichia coli K-12 cells]

Autor: R S, Shakulov, V A, Livshits, G G, Zaigraeva, L F, Lideman, T D, Mukhamed'ianova

Publikováno v: Genetika. 14(5)

Mutants of Escherichia coli K-12 re1A+-strain CP 78 resistant to fusidic acid (Fusr) were isolated and forms sensitive to high concentration of leucine (500 g/ml) were selected. When shifted down from nutrient broth to minimal medium M9 with suppleme
