CGSC Strain#: 4972
Strain Designation: CA3      Source of Strain: S. Brenner
Sex: Hfr    Point of Origin#: 1   Map Position: 96.80   Direction of Marker Transfer: Clockwise
Chromosomal Markers: galE15(GalS), λ^-, e14-, relA1, spoT1
Strain Comments:

• galE15(GalS)-- is Brenner's gal^-_U38, isolated by UV mutagenesis from his strain CA1.
• galE15(GalS)-- G to A transition resulting in an S122F amino acid substitution
• 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.
• GalS = UDPGal accum.toxic if GalKRP+
