格列菌素是 NRPS-PKS 混合天然产物,具有不可逆蛋白酶体抑制剂的作用。多种中链 2(E),4(E)-二烯脂肪酸 N-酰化肽内酰胺核心,并显着增强蛋白酶体抑制效力。我们在大肠杆菌中表达了起始 NRPS 模块 GlbF (C-A-T),并仅在与 8 kDa MbtH 样蛋白 GlbE 共表达时观察到可溶性活性蛋白。 Thr 腺苷酸化并安装为 T 结构域硫酯后,起始缩合结构域利用脂肪酰基辅酶 A 供体酰化 Thr1 氨基并生成脂肪酰基-Thr1-S-泛酰胆碱基-GlbF 中间体,用于随后的链延伸。先前提出通过酰基载体蛋白脂肪酸供体介导,直接利用脂肪酰辅酶A供体对T域束缚氨基酸进行N-酰化可能是NRPS介导的脂肽生物合成中链起始的常见策略。
Glidobactins are hybrid NRPS-PKS natural products that function as irreversible proteasome inhibitors. A variety of medium chain 2(E),4(E)-diene fatty acids N-acylate the peptidolactam core and contribute significantly to the potency of proteasome inhibition. We have expressed the initiation NRPS module GlbF (C-A-T) in Escherichia coli and observe soluble active protein only on co-expression with the 8 kDa MbtH-like protein, GlbE. Following adenylation and installation of Thr as a T-domain thioester, the starter condensation domain utilizes fatty acyl-CoA donors to acylate the Thr1 amino group and generate the fatty acyl-Thr1-S-pantetheinyl-GlbF intermediate to be used in subsequent chain elongation. Previously proposed to be mediated via acyl carrier protein fatty acid donors, direct utilization of fatty acyl-CoA donors for N-acylation of T-domain tethered amino acids is likely a common strategy for chain initiation in NRPS-mediated lipopeptide biosynthesis.
