ilvD132Strain Comments: - glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- hisG1-- This mutation has been reported as either a frameshift or a 36 nt deletion
- 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.
