Divergent architecture of the heterotrimeric NatC complex explains N-terminal acetylation of cognate substrates

The conserved eukaryotic heterotrimeric NatC complex co-translationally acetylates the N-termini of numerous target proteins. Here, the authors provide insights into the catalytic mechanism of NatC by determining the crystal structures of Saccharomyces cerevisiae NatC in the absence and presence of...

Sumario:The conserved eukaryotic heterotrimeric NatC complex co-translationally acetylates the N-termini of numerous target proteins. Here, the authors provide insights into the catalytic mechanism of NatC by determining the crystal structures of Saccharomyces cerevisiae NatC in the absence and presence of cofactors and peptide substrates and reveal the molecular basis of substrate binding by further biochemical analyses.
