The aim is to elucidate the catalytic and regulatory mechanisms of tRNA t6A modification by the KEOPS complex.
Structural analysis of the KEOPS-tRNA complex
Assessment of GAMOS-associated mutations
Identification of functional hotspots within the complex.
The KEOPS complex exhibits specific structural features crucial for tRNA modification.
GAMOS-associated mutations identified at functional hotspots affect the efficiency of modification.
Findings provide new insight into the biochemical roles of the KEOPS complex in cellular function.
Abstract
A activity. GAMOS-associated mutations cluster at functional hotspots within the KEOPS-tRNA complex. This study provides a structural framework for understanding KEOPS mechanism and its cellular roles.
