50, 495-508), three regions which could not be cloned were identified and 
termed gaps A, B and C. Gap A has been shown to contain the gene lpp, coding 
for an outer membrane lipoprotein, which cannot be cloned as an intact ORF
(Nakamura & Inouye (1979), Cell 18, 1109-1117), presumably due to toxicity 
when overexpressed.

The best source of information on E. coli genes is the E. coli genome project!
