Sex: Hfr    Point of Origin#: 45   Map Position: 65.00   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: λ^-, gyrA26(NalR), recA441(ts), relA1, thiE1
Strain Comments:

• gyrA26(NalR)-- was formerly called nalA26.
• recA441(ts)-- formerly tif-1 (temp.-induced filamentation). Not a Rec^- phenotype, "constitutive protease activity" not requiring ss-DNA binding at hi temp.
• thiE1 was formerly called thi-1
• NalR = Nalidix.acidResist.
• ts = Temperature Sensitive
