Yy. Zhang et Mm. Hanna, NUSA CHANGES THE CONFORMATION OF ESCHERICHIA-COLI RNA-POLYMERASE AT THE BINDING-SITE FOR THE 3' END OF THE NASCENT RNA, Journal of bacteriology, 176(6), 1994, pp. 1787-1789
A conformational change in Escherichia coli RNA polymerase induced by
NusA was detected by utilizing photocrosslinking. A change in the bind
ing site for the 3' end of the RNA occurred, and NusA increased intera
ctions of the RNA with the beta subunit of the polymerase. NusA was no
t contacted by the 3' end of the RNA.
