BACKGROUND The ability to produce the same recombinant protein in both prokaryotic and eukaryotic cells offers many experimental opportunities. However, the cloning of the same gene into multiple plasmids is required, which is time consuming, laborious and still may not produce soluble, stable protein in sufficient quantities. We have developed a set of expression vectors that allows for ligati...
The glycosylphosphatidylinositol (GPI)-anchored proteins are widely distributed in eukaryotic cells, from yeasts to mammals. A number of proteins, such as glycosyltransferases, are necessary for GPI anchor biosynthesis. Cloning of genes encoding these proteins is required for analyses of their nature and the biosynthetic pathway. Here we report a new method of expression cloning that is applica...
The advent of systems biology necessitates the cloning of nearly entire sets of protein-encoding open reading frames (ORFs), or ORFeomes, to allow functional studies of the corresponding proteomes. Here, we describe the generation of a first version of the human ORFeome using a newly improved Gateway recombinational cloning approach. Using the Mammalian Gene Collection (MGC) resource as a start...
Synthetic biology and genome-scale protein work both require rapid and efficient cloning, expression and purification. Tools for co-expression of multiple proteins and production of fusion proteins with purification and solubility tags are often desirable. Here we present a survey of plasmid vectors that provide for some of these features with a focus on tools for rapid cloning and traceless ta...
The creation of genome-scale clone resources is a difficult and costly process, making it essential to maximize the efficiency of each step of clone creation. In this review, we compare the available commercial and open-source recombinational cloning methods with regard to their use in creating comprehensive open reading frame (ORF) clone collections with an emphasis on the properties requisite...
proline dehydrogenase (prodh; 1.5.99.8) belongs to superfamily of amino acid dehydrogenase, which plays a significant role in the metabolic pathway from proline to glutamate. the goal of this research was gene cloning and characterization of prodh enzyme from pseudomonas fluorescens pf-5 strain. the gene encoding prodh was isolated by means of pcr amplification and cloned in an iptg inducible t...
A rate-limiting and costly step in many proteomics analyses is the cloning of all of the ORFs for an organism into technique-specific vectors. Here, we describe the generation of a Campylobacter jejuni expression clone set using a high-throughput cloning approach based on recombination in E. coli. The approach uses native E. coli recombination functions and requires no in vitro enzymatic steps ...
We investigate the universal asymmetric cloning of states in a Hilbert space of arbitrary dimension. We derive the class of optimal and fully asymmetric 1→ 3 cloners, which produce three copies, each having a different fidelity. A simple parametric expression for the maximum achievable cloning fidelity triplets is then provided. As a side-product, we also prove the optimality of the 1 → 2 asymm...
Background: Improving the performance of HIV diagnosis assays is one of the most important ways to reduce HIV transmission. Because of the high mutation rate of HIV, it is critical to use the conserved proteins to develop diagnostic immunoassay methods. Because integrase is one of the most conserved proteins of HIV, it may be a good target for this purpose. In this paper cloning, purification a...
Molecular farming has been considered as a secure and economical approach for production of biopharmaceuticals. Human TNF Related Apoptosis Inducing Ligand (TRAIL) as a promising biopharmaceutical candidate has been produced in different expression hosts. However, little attention has been paid to molecular farming of the TRAIL in spite of numerous advantages of plant expression systems. Theref...
