Sex: Hfr    Point of Origin#: 1   Map Position: 96.80   Direction of Marker Transfer: Clockwise
Chromosomal Markers: λ^-, e14-, cysJ43, relA1, spoT1, thiE1, creC510
Strain Comments:

• Reference: M. Jones-Mortimer, Personal Communication, cited in Riordan and Kornberg, below.
• e14--- : Loss of the e14 element makes the strain McrA^-.
• cysJ43-- - the cys allele was formerly thought to be in cysC.
• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• creC510-- The constitutive phenotype is due to an R77P amino acid substitution
• creC510 was formerly called phoM510
• thiE1 was formerly called thi-1
