Strain Comments:

• This strain may also carry sugar markers and supE44.
• leuB6(Am)-- Suppressed by serU suppressor (supH)
• thyA704-- 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.
• uxuB108-- is called uxuB8 in the reference below.
• Am = amber(UAG) mutation
• L? = assignment uncertain
