Patch cloning method for multiple site-directed and saturation mutagenesis
BACKGROUND Various DNA manipulation methods have been developed to prepare mutant genes for protein engineering. However, development of more efficient and convenient method is still demanded. Homologous DNA assembly methods, which do not depend on restriction enzymes, have been used as convenient tools for cloning and have been applied to site-directed mutagenesis recently. This study describe...
متن کاملSaturation site-directed mutagenesis of thymidylate synthase.
We have subjected 12 different codons of a synthetic Lactobacillus casei thymidylate synthase (TS) gene to saturation site-directed mutagenesis to create amino acid "replacement sets" at each of those positions. The target residues were chosen because they are highly conserved and because they are important for the structure and function of the protein as indicated by solution and structural st...
متن کاملSite-Directed Mutagenesis in Human Granulocyte-colony Stimulating Factor, Cloning and Expression in Escherichia coli
Human granulocyte colony stimulating factor (hG-CSF) induces proliferation and differentiation of granulocyte progenitor cells. This glycoprotein is currently being used for treatment of neutropenia, in patients who have undergone bone marrow transplantation. So far, different researchers have tried to enhance hG-CSF biological activity and stability. In this study, Polymerase Chain Reaction (P...
متن کاملSequence saturation mutagenesis (SeSaM): a novel method for directed evolution.
Sequence saturation mutagenesis (SeSaM) is a conceptually novel and practically simple method that truly randomizes a target sequence at every single nucleotide position. A SeSaM experiment can be accomplished within 2-3 days and comprises four steps: generating a pool of DNA fragments with random length, 'tailing' the DNA fragments with universal base using terminal transferase at 3'-termini, ...
متن کاملComplementary annealing mediated by exonuclease: a method for seamless cloning and conditioning site-directed mutagenesis
Traditional cut-paste DNA cloning is often limited by the availability of restriction enzyme sites. Here, we described the complementary annealing mediated by exonuclease (CAME), in which the insert or vector fragment is amplified to carry sequences complementary to the other, and both fragments are modified by exonuleases to create directional single-stranded overhangs. The two recessed DNA fr...
