Abstract
KKT23 is a kinetoplastid-specific kinetochore protein that has a C-terminal GCN5-related histone acetyltransferase domain that acetylates the C-terminal tail of histone H2A. Here, we present the 1H, 13C and 15N resonance assignments for the C-terminal region of KKT23 (KKT23125-348) from Trypanosoma brucei in complex with known cofactors for acetyltransferases, acetyl coenzyme A and coenzyme A. These assignments provide the starting point for detailed investigation of the structure, dynamics and interactions of KKT23 in solution.
