This peptide sequence is found in residues 14 to 30 of P22 N. P22 N is a transcriptional antiterminator that binds to N-utilization (NUT) sites on viral transcripts. P22 N modifies RNA polymerase activity by creating a termination-resistant form of the RNA polymerase complex that is able to continue transcribing the viral transcript.
Soluble in pure water. Avoid repeated freezing and thawing.
