Polyketide synthases (PKSs) have several known editing mechanisms to ensure that non-productive intermediates are removed from the acyl carrier protein (ACP). We demonstrate that CitA, a putative hydrolase in the citrinin biosynthetic gene cluster, removes ACP-bound acyl intermediates. We propose that it serves an editing role in trans.
聚酮合酶(PKSs)有几种已知的编辑机制,以确保非生产性中间体从酰基载体蛋白(ACP)上被去除。我们证明,citrinin生物合成基因簇中的一种假定水解酶CitA可去除与ACP结合的酰基中间体。我们认为它在转位过程中起编辑作用。
