Recombinant E.coli Transcription Termination/antitermination L Factor

• Cat.No.: NusA-391E
• Product Overview: Recombinant NusA was expressed in E.coli and purified by using conventional chromatography techniques, 54 kDa (495 aa).

Specification

• Species: E.coli
• Source: E.coli
• Tag: Non
• Description: NusA is a key component in both Prevention and enhancement of transcriptional termination. It is important in both Rho-dependent and intrinsic termination, as well as in lambda and other phage antitermination systems. The gene was first identified by isolation of the nusAl mutation, which restricts bacteriophage l growth by preventing the antitermination activity of the l N protein. NusA is involved in transcriptional antitermination in the cell. It has been shown to specifically aid in read-through of the RNA polymerase genes rpoB and rpoC, as well as in successful synthesis of the ribosomal RNA genes.
