Helix-Loop-Helix Motif in HIV-1 Rev

Biochemistry, 1994
Circular dichroism (CD) spectra of C-terminal deletion mutants of the HIV-1 Rev protein, Rev M9 delta 14 (missing aa 68-112) and Rev M11 delta 14 (lacking aa 92-112), indicated that Rev contains 46-49 residues in alpha-helical conformation within the N-terminal 71 or 95 amino acids of the 116 residue protein.

De novo Metallonucleases Based on Helix–Loop–Helix Motifs

Chemistry – A European Journal, 2004
AbstractThree new 42‐mer peptides (PR I–III) designed to fold into a hairpin helix–loop–helix motif have been prepared. In the peptide sequence two (PR II–III) or four (PR I) copies of an unnatural amino acid bearing a triazacyclononane metal‐ion binding site (ATANP) have been inserted in appropriate positions to allow the ligand subunits to face each ...

Engineering Magnesium Selectivity in the Helix–Loop–Helix Calcium-Binding Motif

Archives of Biochemistry and Biophysics, 1995
Engineering magnesium selectivity into the helix-loop-helix (hlh) cation binding site is relatively unstudied in the calmodulin superfamily of calcium-regulated proteins, which include parvalbumin, oncomodulin, troponin C, calbindin, and calmodulin. Studies using a 33-residue synthetic peptide model of the hlh cation binding motif have indicated that ...

Interhelical carbon bridging of catalytic helix–loop–helix polypeptide motifs †

Journal of the Chemical Society, Perkin Transactions 2, 2000
Interhelically bridged polypeptides with helix–loop–helix motifs have been synthesised by self-catalysed, site-selective acylation reactions. Lysine residues in the helices have been bridged using the bifunctional N-hydroxysuccinimide ester disuccinimidyl glutarate (DSG).

The yeast regulatory gene PHO4 encodes a helix‐loop‐helix motif

Yeast, 1990
AbstractEvidence is presented, based on sequence comparisons and secondary structure prediction, of the presence of a DNA‐binding and dimerization helix‐loop‐helix motif in the yeast transcription activator PHO4. Interest in the existence of this first known motif in yeast is discussed.
