WebDas Helix-Turn-Helix-Motiv (HTH) ist ein Sekundärstrukturelement in Proteinen. Es ist Bestandteil von DNA-bindenden Proteinen mit sequenzspezifischer DNA-Bindedomäne und setzt sich aus zwei α-Helices zusammen, die durch eine β-Schleife (auch β-turn) verbunden sind. Transkriptionsregulatoren in Bakterien enthalten oft ein HTH-Motiv. WebHelix-loop-helix Consists of alpha helices bound by a looping stretch of amino acids.
