EWH193      Source of Strain:
F- Chromosomal Markers: lacY1
, rpsL8 or rpsL104 or rplL9
, rpoB306Strain Comments:
- thyA3-- 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.
- metK110(ts)-- is a temperature-sensitive mutation in an essential gene.
- glnV44(AS) was formerly called supE44
- glnV44(AS) was formerly called su+II
- AS = amber(UAG) suppressor
- Fs = Frameshift mutation
- LamR = Lambda-resistant
- ts = Temperature Sensitive
