机器学习设计出内在无序蛋白质
Ke Ji Ri Bao· 2025-10-10 23:58
为应对这一挑战,研究团队提出了一种结合物理模型与机器学习技术的新路径。该方法基于"自动微 分"技术——一种常用于深度学习中计算导数的算法,用于追踪输入变量微小变化对输出的影响。他们 利用这一机制,在分子动力学模拟框架下直接优化氨基酸序列,使其具备预定的物理或功能特性。与依 赖大量数据训练的典型人工智能模型不同,该方法依托已有且足够精确的物理模拟体系,通过梯度优化 高效搜索满足特定功能需求的蛋白质序列,如形成柔性连接结构或响应环境变化的能力。 团队强调,目标并非用数据驱动模型替代物理理解,而是将真实的分子行为规律嵌入设计过程,使生成 的蛋白质序列不仅具备功能性,而且其设计过程本身就根植于自然界真实的动力学原理。由此设计出的 蛋白质是"可微分的",意味着每一步优化都建立在对系统物理状态连续、精确调控的基础上,而非依赖 黑箱式的预测。 (文章来源:科技日报) 美国哈佛大学与西北大学研究团队合作,开发出一种新型机器学习方法,能够从无序蛋白质中排序,设 计出具有特定性质的内在无序蛋白质(IDPs),从而突破了当前人工智能(AI)工具在解析约30%人类 蛋白质结构上的局限。该成果发表于最新一期《自然·计算科学》。 这类蛋 ...
