N- and C-Terminal Truncations to Enhance Protein Solubility and Crystallization: Predicting Protein sufficient quantities may not always be achievable if proteins are poorly soluble which is frequently determined by physico-chemical parameters such as intrinsic disorder. It is well known that discrete protein domains often have a greater likelihood of high-level soluble expression and crystallizab

ESPRIT: A Method for Defining Soluble Expression Constructs in Poorly Understood Gene Sequencestarget sequences are poorly annotated, or when there are few similar sequences available for alignments, identification of domains can be problematic. A method called expression of soluble proteins by random incremental truncation (ESPRIT) addresses this problem by high-throughput automated screenin

Optimizing ,-Based Membrane Protein Production Using Lemo21(DE3) or pReX and GFP-Fusionsrain or the pReX T7-based expression vector with membrane proteins C-terminally fused to Green Fluorescent Protein (GFP) greatly facilitates the optimization of membrane protein production yields. Both Lemo21(DE3) and pReX allow precise regulation of expression intensities of genes encoding membrane

A Generic Protocol for Purifying Disulfide-Bonded Domains and Random Protein Fragments Using Fusion roperly folded proteins remains challenging (Sorensen and Mortensen, J Biotechnol 115:113–128, 2005; Correa and Oppezzo, Methods Mol Biol 1258:27–44, 2015). Proteins that contain disulfide bonds (e.g., cytokines, growth factors) are often particularly difficult to purify in soluble form and still ne

Split GFP Complementation as Reporter of Membrane Protein Expression and Stability in ,: A Tool to Ee. In this chapter, we describe a protocol to engineer SteT, the amino acid transporter of ., in order to improve its heterologous expression in . and its stability in detergent micelles. We built a library of 70 SteT mutants, combining a random mutagenesis protocol with a split GFP assay as reporte
