, thiE1Strain Comments:
- PO 59 is sometimes called OR11, and the strain of origin is sometimes called Hfr OR11.
- This strain should be maintained on medium containing thi, met, tryp, leu and lacking ade, pro.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- purE42-- :Strains with this marker are derivatives of Χ148 and may carry malA38LAMR and a suppressor of the Mal- phenotype, sup-78,near his.
- recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
- glnV44(AS) was formerly called supE44
- glnV44(AS) was formerly called su+II
