The carboxy-terminal 14 amino acids of phage lambda N protein are dispensable for transcription antitermination.

摘要

The analogous N proteins encoded by lambdoid bacteriophages lambda, 21, and 22 are very different in amino acid sequence, except at their carboxy-terminal ends. Since N lambda remains functional despite the deletion of most of its terminal region of homology to N21, that region of homology cannot represent a region of conserved function.
