A summary of the major pathways of N-terminal processing in eukaryotes, showing the four different termini. 1: Uncleaved and unacetylated Met-Xxx- N-termini; 2: Cleaved and unacetylated Xxx-N-termini; 3: Uncleaved and NatB/NatC acetylated Ac-Met-Xxx- N-termini; 4: Cleaved and NatA acetylated Ac-Xxx-N-termini. See Table 1 and Figure 2 for more detail.
