Molecular analysis of the gene cluster involved in the production and secretion of enterocins 1071A and 1071B and of the genes responsible for the replication and transfer of plasmid pEF1071.

Plasmid pEF1071 (9328 bp), bearing the structural genes of enterocins 1071A and 1071B, had been sequenced and nine genes were identified. The genes responsible for the production and transfer of enterocins 1071A and 1071B are arranged in two operons. The first operon (EntABI) contains the genes ent1071A, ent1071B and entI that encodes enterocin 1071A… CONTINUE READING
