It was subsequently post-translationally modified by the McbBCD complex to yield nine heterocycles, where F6N equals oxazole and is derived from Gly-Ser, F75 equals thiazole and is derived from Gly-Cys, OTZ equals oxazole-thiazole and is derived from Gly-Ser-Cys, TOZ equals thiazole-oxazole and is derived from Gly-Cys-Ser. Each mono- or bis-heterocycle (where present) was treated as a pseudo-amino acid for refinement purposes. The numbering system used in this PDB file relates to the processed peptide where each pseudo-amino acid is treated as a single residue making the overall sequence nine residues shorter.
