Heterologous expression of the citrinin polyketide synthase, CitS, plus the tailoring enzymes CitA–CitE fromMonascus ruberhas fully elucidated the biosynthetic pathway to citrinin for the first time, showing relationships to tropolone, azaphilone and sorbicillinoid biosynthetic pathways in fungi.
He et al. (2015) studied this question.
