WHEN MADE INTO AN OFFICIAL PAGE:

  • LINK FROM RNA motifs PAGE!!!!
  • add Redirect from K-turn motif
  • add redirect from GA motif
  • add redirect from kink-turn
  • add redirect from k-turn


The kink-turn motif
A common RNA structural motif that consists of helix–internal loop–helix motif .


Contents

Introduction

Originally identified in the course of analyzing the large ribosomal subunit[1], the motif was identified in other RNAs. Particular instances are referred to as the the GA motif [2] A motif that includes the A-minor motif. Many K-turns bind proteins; however, they also mediate RNA tertiary structure interactions.

Structures Containing the Motif

Drag the structure with the mouse to rotate
  • The Large Ribosomal Subunit contains 8 identified kink-turns: ,Kt-58 of 3cc2. MAKE The location of all of them in the subunit. To see them in greater detail following the appropriate links on this page at a structural database for k-turn motifs in RNA by the Lilley group[3].
  • 1e7k – the human spliceosomal and small nucleolar RNA-binding 15.5kD protein bound to a U4 spliceosomal RNA fragment[4]
  • 1rlg - A. fulgidus small ribonucleoprotein particle box C/D RNA complexed with L7Ae[5]
  • 2hvy - Pyrococcus furiosus small ribonucleoprotein particle H/ACA box RNA from [6]
  • 1u6b, 1zzn, 3bo2, 3bo3, 3bo4, and 3iin - Azoarcus group I intron has a 'reverse' kink-turnPUT A SCENE HERE OF ALIGNMENT OF THIS WITH KT-T COLORED SO CLEAR WHAT IS WHAT BETTER THAN SEEN AT KINK-TURN DATABASE[7][8][9][10]
  • 1t0k - S. cervisiae L30e bound to its pre-mRNA[11]
  • 1nkw – The Large Ribosomal Subunit From Deinococcus radiodurans[12]
  • Small Ribosomal Subunit
