A cluster of cell division genes maps to the terC region of the chromosome of Escherichia coli K-12

Thirty-nine cell division mutants were isolated in Escherichia coli K-12 and were mapped in the terminus region of the chromosome, between 33.5 and 36 min. They were obtained by two different approaches involving specific mutagenesis of the terC region. The mutants could be divided into eight classes (I to VIII) based on their map position and phenotype at the restrictive temperature, and constitute a new cell division gene cluster.
