CGSC Strain#: 5924
Strain Designation: JG110     
Source of Strain: J. Gross
Sex: F-
Chromosomal Markers: λ-,
thyA36,
IN(rrnD-rrnE)1,
metE70,
polA5,
deoC2Strain Comments: - thyA36-- Strains with this marker must have their medium supplemented with thymine (25ug/ml). This is true even for rich medium such as LB. Otherwise thymine starvation can lead to thymineless death.
- IN(rrnD-rrnE)1-- Inverts the region between rrnD (73.74 min) and rrnE (90.66 min)
- polA5-- polymerase altered pH opt., altered template specificity, lower overall activity; Exo-greater than normal levels. see G. and K.
