Helix turn helix transcription factor
Web1 nov. 1998 · An important class of helix-turn-helix proteins are the homeodomain proteins (Fig. 5A, B). The homeodomain is a stretch of about 60 amino acids that is highly conserved in a class of genes called homeotic genes, which play a critical role in the development of organisms. In Drosophila at least 60 homeodomain proteins have been identified. WebDNA-binding proteins can incorporate such domains as the zinc finger, the helix-turn-helix, and the leucine zipper (among many others) that facilitate binding to nucleic acid. There are also more unusual examples such as …

WebThe HTH motif has been found in a wide range of prokaryotic and eukaryotic transcription factors. The motif is composed of approximately 21 residues which fold into two helices, known as helix-2 and helix-3, which dock onto one another at a 120° angle with an intervening three- or four-residue turn (Figure 1). 7–9 The recognition helix, helix-3, is … WebStart Over You searched for: Subject Basic Helix-Loop-Helix Transcription Factors Remove constraint Subject: Basic Helix-Loop-Helix Transcription Factors Genre Articles Remove constraint Genre: Articles Year 1990 to 1994 ...

Web1 apr. 2005 · The helix-turn-helix (HTH) domain is a common denominator in basal and specific transcription factors from the three super-kingdoms of life. At its core, the domain comprises of an open tri-helical bundle, which typically binds DNA with the 3rd helix. WebWe present here a reassessment of bacterial helix-turn-helix regulator diversity in different organisms from a multidisciplinary perspective, on the interface that links metabolism, ecology and phylogeny, further sustained by a statistically based approach.
WebIn general, transcription factors (including this type) are dimeric, each with one helix containing basic amino acid residues that facilitate DNA binding. [6] In general, one helix is smaller, and due to the flexibility of this loop, allows dimerization by folding and packing against another helix.
