Introduction to β-Barrel Proteins

β-barrel proteins, also known as outer membrane proteins (OMPs), play a significant role in regulating signal transduction and membrane formation. Previous studies have shown that a number of strands, such as NspA, OmpA, OmpX, PagP, EstA, LpxR, as well as NalP, have been observed in all OMPs. The results suggest these strands are essential to a wide variety of biological functions, including acting as enzymes, transporters. Meanwhile, the structure of β-barrel proteins has been identified in recent years. For example, EstA has been considered as an attractive tool for mediating cell motility and surface protein presentation. Furthermore, many advances have been made on the crystallization of β-barrel proteins in native-like lipid environments. A series of assays, such as bicelle crystallization kit, lipidic cubic phase (LCP), have been developed for screening crystallization at a fast turnaround time. Additionally, the structure analysis of target proteins has led to more novel β-barrels in protein design and protein engineering for disease therapy.

The structure analysis of β-barrel proteins has aroused much attention and has been widely used for new β-barrel protein design and protein engineering. A panel of crystallization and sample preparation techniques have been established to predict the structure of β-barrel proteins. As a consequence, Creative Biolabs provides a range of services on analyzing the structure of current β-barrel to design novel β-barrel proteins for disease treatments. Up to now, we have developed several methods to predict their 3D structures, test their functions, as well as determine homogeneous samples. For instance, recent reports conducted by our labs have demonstrated that our methods can be broadly used to engineer protein nanopores by using β-barrel proteins. These methods can help our clients understand the organizing principle of β-barrel proteins. Besides, we offer a unique platform to design new structures of β-barrels for our worldwide customers to meet their requirements on drug delivery for disease therapy.
