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 |

|
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. | |||
|
