Abstract

Synergies between surfactants and proteins are found everywhere in everyday life. Beneficial interactions are exploited in fields such as food processing, pharmaceutical production, and laundry, leading to better products and lower energy consumption. Nevertheless, there is still room for improvement regarding sustainability. Here, biosurfactants (BS) are an attractive alternative to petrochemical surfactants. Insights into BS-protein interactions can help replacing traditional surfactants with BS and uncover new opportunities. Here, we review recent work on proteins' interactions with BS, with focus on the self-assembly of protein:BS complexes and BS’ effects on enzymatic activity. Generally, interactions are milder than those with traditional ionic surfactants, leading to modest effects on protein structure and self-assembly, while enzymatic inhibition is generally observed above BS' critical micelle concentration. Mild interactions between proteins and BS show promise in forming functional complexes with proteins, however, further studies are required to understand and minimize the detrimental effects that do occur.

蛋白质和生物表面活性剂:结构、功能和最新应用
表面活性剂和蛋白质之间的协同作用在日常生活中随处可见。在食品加工、药品生产和洗衣等领域利用了有益的相互作用,从而产生更好的产品和更低的能耗。然而,在可持续性方面仍有改进的余地。在这方面,生物表面活性剂(BS)是石化表面活性剂的一个有吸引力的替代品。对BS-蛋白质相互作用的深入了解可以帮助用BS取代传统的表面活性剂,并发现新的机会。本文综述了近年来蛋白质与BS相互作用的研究进展,重点介绍了蛋白质的自组装:BS复合物和BS对酶活性的影响。通常,与传统离子表面活性剂的相互作用较温和,导致对蛋白质结构和自组装的影响不大,而在BS的临界胶束浓度以上通常观察到酶抑制。蛋白质和BS之间的轻微相互作用显示出与蛋白质形成功能复合物的希望,然而,需要进一步的研究来了解和最小化确实发生的有害影响。

期刊介绍: Current Opinion in Colloid and Interface Science (COCIS) is an international journal that focuses on the molecular and nanoscopic aspects of colloidal systems and interfaces in various scientific and technological fields. These include materials science, biologically-relevant systems, energy and environmental technologies, and industrial applications. Unlike primary journals, COCIS primarily serves as a guide for researchers, helping them navigate through the vast landscape of recently published literature. It critically analyzes the state of the art, identifies bottlenecks and unsolved issues, and proposes future developments. Moreover, COCIS emphasizes certain areas and papers that are considered particularly interesting and significant by the Editors and Section Editors. Its goal is to provide valuable insights and updates to the research community in these specialized areas.
