Allele Nt change(s) AA change(s) Phenotype: Type Phenotype: Description Reference Availability Comments

parC1215

G2199A

G703D

Growth Phenotype

  • ts @ 42
  • Chromosome partitioning phenotype
  • Filamentation

PMID:2170028[2], PMID:2842295[3]

actual nucleotide mapping was referenced in [2]

parC10

Y120H

DNA nicking independent of ATP hydrolysis

PMID:9077455[4]

parCL80

S80L

Resistant to

Quinolone resistance

PMID:8524852[5]

The mutation conferred increased resistance toward quinolones, specifically norfloxcin. See figure 3. chEBI:23765

parCL80 gyrAr

parC S80L gyrA S83L

Resistant to

quinolone resistance

PMID:8524852[5]

The double mutation conferred a 6 fold increase of quinolone resistance compared to the mutation with only the gyrAR mutation. See figure 4 for experimental results. chEBI:23765

Notes

  • The partitioning defect comes from the inability of these cells to partition the nucleoids into daughter cells. This results in filamentous cells with a cluster of nucleoid at the center and subsequent DNA-free cells.
  • The Keio collection[6] lists a deletion of parC, which is an essential gene. There is a duplication of the parC region.[7].
  • Suppressors of the parC1215 mutation when expressed at high-copy[8]:
    • topB
    • dnaN (β subunit of the DNA polymerase holoenzyme)
    • spcA (suppressor of parC A- will be renamed setB)
