SAIRGA (TFA)(CAT: I040231) is a synthetic hexapeptide derived from the bacteriophage phi3T, known for its role in phage-host communication. It specifically interacts with phAimR, a transcriptional regulator in the bacterial cytosol, to induce lysogeny—a dormancy-like state where the phage genome integrates into the host without immediate lysis. This quorum-sensing-like mechanism enables phages to modulate infection strategy based on host population density. SAIRGA (TFA) is a valuable molecular tool for studying phage signaling pathways, host-phage interactions, and regulatory mechanisms underlying lysogeny in Bacillus subtilis and related bacterial systems.
