The diversity of alleles at the hsd locus in natural populations of Escherichia coli.

Genetics - 1 Aug 1995

Barcus V A, Titheradge A J, Murray N E

Abstract excerpt

In enteric bacteria three discrete families of type I restriction and modification systems (IA, IB and ID) are encoded by alleles of the serB-linked hsd locus. Probes specific for each of the three families were used to monitor the distribution of related systems in 37 of the 72 wild-type Escherichia coli strains comprising the ECOR collection. All 25 members of group A in this collection were screened; 12 were...
