M.C. CappelloOther Designations:
F141 Plasmid Markers/Mutations: Chromosomal Markers: leuB6
, metB1Strain Comments:
- F141 has also been called KLF41.
- This strain should be maintained on medium containing his, leu, met and lacking arg. This strain grows slowly.
- leuB6(Am)-- Suppressed by serU suppressor (supH)
- 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
- recA1-- : Missense mutation, altered isoelectric point. Sequenced: G to A for Nuc. 720 (Gly 160 Asp).
