The E. coli K12 strain HB101 (DSM 1607, ATCC 33694)) is one of the grandfathers in molecular biology. It was constructed by complementation analysis of a K12 strain with a B strain. Thus HB101 carries about 10% of the B strain chromosome. Its genotype is F- leuB6 proA2 recA13 thi1 ara14 lacY1 galK2 xyl5 mtl1 rpsL20 supE44 hsdS20 lambda- rB-mB-. HB101 deviates to a big extend from the prototypic K12 strain W3110. On the other hand HB101 was the basis for the construction of many contemporary laboratory strains.
