Figure 2

Six modular architectures for ferrichrome synthetase NRPSs. Types III, IV, and V are in the NPS2 lineage while Types I, II, and VI are in the NPS1/SidC lineage. A: adenylation domain, T; thiolation domain, C; condensation domain. dA; degenerate A domain. Bars above boxes indicate complete modules. Circles indicate incomplete modules and/or a T-C unit. Superscript 'a' indicates partial gene.
