Sex: Hfr    Point of Origin#: 1   Map Position: 96.80   Direction of Marker Transfer: Clockwise
Chromosomal Markers: λ^-, e14-, relA1, spoT1, thiE1, opgB202::Tn10
Strain Comments:

• e14--- : Loss of the e14 element makes the strain McrA^-.
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• opgB202::Tn10-- cotransduces 34% with serB and 13% with thr and ca. 50% with hsd. Shown by PCR analysis (Nichols et al.) to be within opgB at nucleotide 4,595,002 (99.0 min.).
• opgB202::Tn10 was formerly called
