Plastics like polyurethanes (PUs) and polyamides (PAs) largely resist biodegradation. Herein, we report the first crystal structure of the metagenomic urethanase UMG-SP-1. Subsequent engineering yielded variants with up to 8-fold enhanced activity on various urethanes and amides. UMG-SP-1 variants partially degraded a model thermoplastic polyester-PU and nylon 6, highlighting its applicability for the biodegradation and recycling of PU and PA.

宏基因组氨基甲酸酯酶的结构解析及其增强水解特性的工程



聚氨酯 (PU) 和聚酰胺 (PA) 等塑料在很大程度上难以生物降解。在此,我们报告了宏基因组氨基甲酸酯酶 UMG-SP-1 的第一个晶体结构。随后的工程产生了对各种氨基甲酸酯和酰胺的活性增强高达 8 倍的变体。 UMG-SP-1 变体部分降解了一种热塑性聚酯-PU 和尼龙 6 模型,突出了其对 PU 和 PA 生物降解和回收的适用性。
