Abstract
In this chapter, the first study of a KS domain immediately downstream of a NRPS module is reported. Using full-length acyl precursors the substrate specificity of BaeJ KS1 from the bacillaene trans-AT PKS was examined. BaeJ KS1 is the first PKS module in the biosynthesis of bacillaene, and is believed to accept a glycine-derived intermediate incorporated by the previous NRPS module. KS1 is positioned in a phylogenetic clade with other amino-acid accepting KS domains, of which the majority accept a glycine intermediate.
