HHsearch alignment for GI: 254780666 and conserved domain: TIGR01951

>TIGR01951 nusB transcription antitermination factor NusB; InterPro: IPR011605 The NusB protein is involved in the regulation of rRNA biosynthesis by transcriptional antitermination. The antitermination proteins of Escherichia coli are recruited in the replication cycle of Bacteriophage lambda, where they play an important role in switching from the lysogenic to the lytic cycle. The solution structure indicates that the protein folds into an alpha/alpha-helical topology consisting of six helices; the arginine-rich N-terminus appears to be disordered .; GO: 0003715 transcription termination factor activity, 0006353 transcription termination.
