Protein
AimR transcriptional regulator
Organism
Bacillus phage SPbeta
Function
Transcriptional regulator which is part of the latency-replication switch system that decides at the onset of infection whether to replicate and lyse the host or to lysogenize (latency) and keep the host viable. Activates the transcription of the aimX locus. Transcriptional activation of aimX seems to lead to the productive viral replication (lytic cycle), aimX possibly acting as a regulatory non-coding RNA.
