This is a helical domain, also known as 'Fingers subdomain', found in the bacteriophage N4 virion RNA polymerase [1]. This domain possesses two essential functions of the RNAP: the N-terminal part plays a role in the nucleotide addition cycle, whereas the C-terminal part is involved in promoter recognition [2]. A swing motion of the N-terminal part of the Fingers is coupled with nucleotide addition, translocation of the DNA-RNA hybrid, and downstream double-strand DNA opening.	Domain

This domain is found in Virion DNA-directed RNA polymerase from Bacteriophage N4 (vRNAP), responsible for the transcription of the early region of the double-stranded linear DNA genome of the lytic coliphage. This entry represents a short insertion that forms a globular module named plug, which blocks the activity of the protein [1-3].	Domain
