CGSC Strain#: 5379
Strain Designation: WP2 hcr^-      Source of Strain: R. Hill
Other Designations: WP2 uvrA^-
Other Designations: WP2_S
Other Designations: AC5379
Sex: F- Chromosomal Markers: lon-11, sulA1, trpE65(Oc), uvrA155
Strain Comments:

• The trpE65 derivative of B/r has been called WP2 and the uvrA155 derivative of that strain WP2_S.
• This is a derivative of E. coli B/r. uvrA155 was formerly called hcr^-.
• lon-11-- is a mutation of an E. coli B gene caused by an IS186 insertion in the promoter. All derivatives of Witkin's B wildtype carry this lon mutation.
• Oc = ochre(UAA) mutation
