清华研究出蛋白质镜像DNA拷贝,或能有效对抗病毒

2016-05-21 佚名 生物谷 Bioon.com

清华大学研究人员创造出与生命功能密切相关的蛋白质镜像,拷贝DNA并将其转化成RNA,这是制造能更有效地对抗病毒入侵的反向版本分子的关键步骤。 虽然一些“手性”分子自然存在于正常和反向形式中,但基本大部分的生命都证明DNA细胞向右扭曲,病毒和酶已在这些模板里发展到目标生命,因此目前最盛行的理论是人造镜像版DNA在自身机能正常运行时还能阻止病毒入侵。 近些年来,科学家一直在制造镜像DNA,因此

清华大学研究人员创造出与生命功能密切相关的蛋白质镜像,拷贝DNA并将其转化成RNA,这是制造能更有效地对抗病毒入侵的反向版本分子的关键步骤。

虽然一些“手性”分子自然存在于正常和反向形式中,但基本大部分的生命都证明DNA细胞向右扭曲,病毒和酶已在这些模板里发展到目标生命,因此目前最盛行的理论是人造镜像版DNA在自身机能正常运行时还能阻止病毒入侵。

近些年来,科学家一直在制造镜像DNA,因此清华大学的研究人员一直在控制他们实验的进度,一方面,他们必须要建立自己的DNA反向聚合酶拷贝,这将极大减缓整个进程,但另一方面,他们又必须加快进度来使整个过程实现收益。但生物化学公司早已瞄准分子镜像的获利空间,以使其在破坏分子酶不降解的情况下能更有效地在人体内发挥作用。
