Helix turn helix motiv
WebOnce the initial turn has been established, two mechanisms have been proposed as to how the rest of the beta-hairpin folds: a hydrophobic collapse with side-chain level rearrangements, or the more accepted zipper-like mechanism. [4] The β-hairpin loop motif can be found in many macromolecular proteins.

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.
WebThe leucine zipper is formed by amphipathic interaction between two ZIP domains. The ZIP domain is found in the alpha-helix of each monomer, and contains leucines, or leucine-like amino acids. These amino acids are spaced out in each region's polypeptide sequence in such a way that when the sequence is coiled in a 3D alpha-helix, the leucine ...

Helix-turn-helix is a DNA-binding protein (DBP). The helix-turn-helix (HTH) is a major structural motif capable of binding DNA. Each monomer incorporates two α helices, joined by a short strand of amino acids, that bind to the major groove of DNA. The HTH motif occurs in many proteins that regulate … Meer weergeven The discovery of the helix-turn-helix motif was based on similarities between several genes encoding transcription regulatory proteins from bacteriophage lambda and Escherichia coli: Cro, CAP, and λ repressor, which were … Meer weergeven The helix-turn-helix motif is a DNA-binding motif.
