SurE is a new, stand-alone thioesterase (TE) offloading the non-ribosomal peptide (NRP) assembly line found in surugamide biosynthesis. It is homologous to penicillin binding protein (PBP) and capable of cyclizing two structurally unrelated substrates derived from two different NRP assembly lines, highlighting the broad substrate tolerance of the SurE offloading cyclase.
SurE 是一种新型的、独立的硫酯酶 (TE),可卸载在 surugamide 生物合成中发现的非核糖体肽 (NRP) 装配线。它与青霉素结合蛋白 (PBP) 同源,能够环化来自两个不同 NRP 装配线的两个结构上不相关的底物,突出了 SurE 卸载环化酶的广泛底物耐受性。
