Glucose- and glucokinase-controlled mal gene expression in Escherichia coli.

abstract：:The rep gene function of Escherichia coli is essential for the replication of P2 and phiX174 double-stranded deoxyribonucleic acid (DNA). Compared with isogenic rep(+) strains, rep mutants show the following characteristics: larger cell size, more DNA per cell, and a slightly lower DNA/mass ratio. The replicating rep ...
