CGSC Strain#: 7160
Strain Designation: CCMB1001      Source of Strain: Bhargava
Sex: Hfr    Point of Origin#: 2A   Map Position: 12.20   Direction of Marker Transfer: Counterclockwise
Chromosomal Markers: garB10, fhuA22, ompF627(T2R), fadL701(T2R), relA1, pitA10, spoT1, pst-9, mcrB1, creC510, lyt-1(ts)
Strain Comments:

• spoT1-- In addition to the 6bp insertion, there is a C to T transition resulting in an H257Y substitution.
• pst-9-- pstA or B
• creC510-- The constitutive phenotype is due to an R77P amino acid substitution
• creC510 was formerly called phoM510
• pst-9 was formerly called phoT9
• Const = constitutive
• T2R = T2 Resistant
• ts = Temperature Sensitive
