The Q motif: a newly identified motif in DEAD box helicases may regulate ATP binding and hydrolysis.

Molecular cell - 1 Jan 2003

Tanner N Kyle, Cordin Olivier, Banroques Josette, Doère Monique, Linder Patrick

Abstract excerpt

SF1 and SF2 helicases have structurally conserved cores containing seven to eight distinctive motifs and variable amino- and carboxyl-terminal flanking sequences. We have discovered a motif upstream of motif I that is unique to and characteristic of the DEAD box family of RNA helicases. It consists of a 9 amino acid sequence containing an invariant glutamine. A conserved phenylalanine occurs 17 aa further...
