Fig. 3: Genetic organization of N-acyl amino acid synthase-encoding genes in the analyzed genomes and structure of isolated N-acyl (dehydro)tyrosine or phenylalanine derivatives.

Only genes putatively involved in the biosynthesis of tyrazolones, thalassotalic acids, kyonggic acids, and stieleriacines are shown. The analysis is based on the RefSeq-annotated genomes available from NCBI (locus tags are provided on the arrows). For simplicity, the length and variability of the acyl chain (R) is omitted.
