C600-T44      Source of Strain:
Goldthwaite & JacobOther Designations:
C600 44 GT19Other Designations:
F- Chromosomal Markers: thr-1
, thiE1Strain Comments:
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- glnX44(AS)-- Mutation is a C to T transition at nucleotide 34 (3rd position of the anticodon)
- e14--- : Loss of the e14 element makes the strain McrA-.
- recA441(ts)-- formerly tif-1 (temp.-induced filamentation). Not a Rec- phenotype, "constitutive protease activity" not requiring ss-DNA binding at hi temp.
- glnX44(AS) was formerly called supE44
- glnX44(AS) was formerly called su+II
- glnX44(AS) was formerly called glnV44
- thiE1 was formerly called thi-1
- Am = amber(UAG) mutation
- AS = amber(UAG) suppressor
- glpc = constitutive expr.glp regulon
- ts = Temperature Sensitive
