tsx mutation in P1807

Sensitivity to

Reduced sensitivity toward albicidin.

PMID:2191080

See Figure 1 B for full experimental results.

tsx mutation in strain P1807

Metabolic uptake

Mutation to the tsx region caused a reduced uptake of nucleoside.

PMID:2191080

See figure 2 for full experimental results.

tsx mutation in strain GP4

Metabolic uptake

Mutation to the tsx region caused a reduced uptake of ablicidin.

PMID:2191080

These results support the theory that ablicidin resistance is due to reduced uptake of the antibiotic. See figure 3b for experimental results.

tsx- in P407

Resistant to

Resistance to Bacteriophage T6

PMID:786267

Mutation to the tsx gene confers resistance to phage T6, possibly by reducing the production of a protein thought to be involved in phage binding, tsx-protein.

tsx--con- in P1731

Resistant to

Resistance to Bacteriophage T6

PMID:786267

A double mutation to the tsx and con gene confers resistance to phage T6, possibly by reducing the production of a protein thought to be involved in phage binding, tsx-protein.

tsx- in P407

Resistant to

Resistance to Colicin K

PMID:786267

Mutation to the tsx gene confers resistance to Colicin K possibly by reducing the production of a specific protein, tsx-protein.

tsx--con- in P1731

Resistant to

Resistance to Colicin K

PMID:786267

A double mutation to the tsx and con gene confers resistance to Colicin K, possibly by reducing the production of a protein thought to be involved in phage binding, tsx-protein.

tsx-2 in strain KG16

Resistant to

Resistance to strain Phage T6

PMID:6808961

tsx-2 class of mutants were resistant to bacteriophage T6. This was also seen in strain KG19.

tsx-2 in strain KG16

Resistant to

Resistance to Colicin K

PMID:6808961

tsx-2 class of mutants became more resistant to Colicin K. This was also seen in strain KG19.

tsx-1 in strain GG24

Resistant to

Resistance to strain Phage T6

PMID:6808961

tsx-1 class of mutants developed an increased resistance toward bacteriophage T6. This was also seen in strain GG26.

tsx-1 in strain GG24d

Resistant to

Resistance to Colicin K

PMID:6808961

tsx-2 class of mutants became more resistant to Colicin K. This was also seen in strain GG24.

tsx-2 in strain KG16

Growth Phenotype

Muciod growth

PMID:6808961

It was found that the tsx-2 class of mutants produced a Muciod type growth configuration. This included strain KG19.

tsx-2 in strain KG16

Sensitivity to

Increased sensitivity to Neomycin.

PMID:6808961

It was found that the tsx-2 class of mutants became increasingly sensitive to aminoglycosides Neomycin and Kanamycin. This included strain KG19.

tsx-2 in strain KG16

Sensitivity to

Increased sensitivity to Kanamycin.

PMID:6808961

It was found that the tsx-2 class of mutants became increasingly sensitive to aminoglycosides Neomycin and Kanamycin. This included strain KG19.

tsx-2

Sensitivity to

The tsx-2 mutation caused increased sensitivity toward the antibiotic nalidixic acid.

PMID:6808961

Experimental Strain: KG16
