Tryptophan RNA-binding Attenuator Protein Inhibitory Protein
Tryptophan RNA-binding attenuator protein inhibitory protein (Anti-TRAP protein or AT) is a short protein encoded by the rtpA in Bacillus. Synthesis of anti-TRAP is induced by uncharged tryptophan tRNA. Anti-TRAP binds to TRAP and inhibits its binding to the tryptophan operator leader. This causes the anti-terminator loop to form and the tryptophan operon to be transcribed.

Famous quotes containing the word protein:
“Firm-style bean curd insoles cushion feet, absorb perspiration and provide more protein than meat or fish innersoles of twice the weight. Tofu compresses with use, becoming more pungent and flavorful. May be removed when not in use to dry or marinate. Innersoles are ready to eat after 1,200 miles of wear. Each pair provides adult protein requirement for 2 meals. Insoles are sized large to allow for snacks. Recipe booklet included.”
—Alfred Gingold, U.S. humorist. Items From Our Catalogue, Tofu Innersoles, Avon Books (1982)
