Structure of cacaoidin before (top) and after (bottom) the Post-Translational Modifications (PTMs). In the modified cacaoidin, absolute configuration for NMe2Ala(S)-1 is tentatively proposed as (2S) (equivalently, d-Ala). The amino acids modified by biosynthetic enzymes are colored in pink, the glycosylated tyrosine is colored in yellow, and the non-modified amino acids are colored in blue.
