, metB1Strain Comments:
- thyA56-- 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.
- spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
