In addition to the cryptic lambdoid prophage genes that are known to reside at the rac locus in Escherichia coli K12 strains, a second cryptic lambdoid prophage has been located near the gal operon. This prophage was shown to contain DNA that is homologous to the QSR genes of lambda phage.
除了已知存在于大肠杆菌K12菌株rac位点的隐秘λ样原噬菌体基因外,第二个隐秘λ样原噬菌体已定位在gal操纵子附近。该原噬菌体被证明含有与λ噬菌体的QSR基因同源的DNA。
