Figure 1. Biosynthesis of nonproteinogenic amino acids used as building blocks of nonribosomal peptides. Biosynthesis pathways of methylproline (2) (a), α-methyl-l-serine (8) (b) and nitrotyrosine (10) (c) used as building blocks of griselimycin (1), JBIR-34 (6), −35 (7) and rufomycin (9), respectively, are shown. KG, alpha-ketoglutarate; 5,10-MTHF, 5,10-methylenetetrahydrofolate; THF, tetrahydrofolate; SC, succinate.
