Restriction endonuclease analysis of the ilvGEDA operon of members of the family Enterobacteriaceae.
نویسندگان
چکیده
Four of the genes required for the biosynthesis of isoleucine and valine form the ilvGEDA operon in Escherichia coli K-12 and Salmonella typhimurium. The structural relationship of these genes was examined in eight other members of the family Enterobacteriaceae by genomic Southern blot hybridization. These genes are contiguous in all the strains examined, and specific restriction sites appear to be highly conserved, indicating the possible functional importance of the DNA sequences of which they are part.

The DNA sequence of the promoter-attenuator of the ilvGEDA operon of Salmonella typhimurium.
The isolation of a lambda gt . ilvGEDA . S.t. hybrid transducing phage has permitted the characterization of the promoter-attenuator region of the ilvGEDA operon of Salmonella typhimurium. In vitro transcription and Southern hybridization indicate that the promoter-attenuator resides on a 400 nucleotide Rsa I restriction fragment. DNA sequence analysis shows only seven base pair differences exi...

متن کاملMolecular analysis of the S1 gene of vaccine strains of infectious bronchitis virus using reverse transcriptase-polymerase chain reaction and restriction fragment length polymorphism
Infectious bronchitis virus (IBV) is an acute and contagious viral disease of poultry that affects different systems, including the respiratory tract in particular. IBV causes major economic losses in the poultry industry globally. Due to antigenic variation of the causative agent, control of the disease is difficult. To control the disease, many vaccines that belong to different serotypes are...

The polymerase chain reaction (PCR) as applied to detection of a foreign DNA in clinical specimens could provide a sensitive instrument for rapid detection of viral DNA persisting in tissues of patients suspected of latent infection. Human cytomegalovirus (HCMV) DNA was found in arterial plaques of patients with atherosclerotic lesions using a PCR assay with nested primer oligonucleotides ...
