Structural features of nonribosomal peptide synthetase enzymes. Nonribosomal peptide synthetase enzymes can be subdivided in modules, each incorporating one amino acid. Each module consist of three domains: adenylation (A) domain, peptidyl carrier protein (PCP) domain, and condensation (C) domain, which carry out the synthesis of nonribosomal peptides; the epimerization (E) domain and thioesterase (TE) domain is also represents. In this figure, surfactin biosynthesis was exemplified
