Abstract
Attempts to characterize thegrpD55 mutation ofEscherichia coli have led us to conclude that the gene had been assigned an incorrect map position. The mutation was found to cotransduce withmalF3089:: Tn10 (at ∼91.5 min) and adnaB-expressing plasmid was able to complement fully thegrpD55 defect in λ replication. These studies strongly suggest thatgrpD55 is an allele ofdnaB and is localized near 92 min on theE. coli linkage map.
