A high density lipoprotein (HDL)-linked enzyme with antioxidant and antiatherogenic properties, paraoxonase1(PON1), prevents the formation of atherosclerotic lesions in humans. In the present study, a recombinant hPON1 gene was produced using a small ubiquitin-related modifier (SUMO) fusion protein expression system. To that end, the hPON1 gene was amplified from human liver-ready cDNA, cloned into the expression vector pET SUMO, and expressed in Escherichia coli BL21 (DE3).

In this study, the DNA fragment encoding for the C-terminus domain of the AopB from Aeromonas hydrophila AH-1 was cloned into pET-M expression vector and expressed in Escherichia coli BL21 (DE3) host cells. The recombinant AopB-C-terminus domain was successfully purified using immobilized nickel affinity chromatography as a soluble form. Crosslinking analysis among AopB-C-terminus molecules in solution showed that this domain existed as a mixture of tetramer, trimer, dimer, and monomer forms.

RNA polymerase II (Pol II) is a 12 subunit protein complex from yeast to human that is required for gene expression. Gdown1 containing Pol II [Pol II (G)] is a special form of Pol II that is catalytically inactive and heavily depends on the 30-subunit Mediator complex for its activator and basal dependent function in vitro. Here we report for the first time, the identification and the generation of a 15-subunit human Mediator complex via the novel multibac baculovirus expression system that is fully responsive to Pol II (G).

The σB protein of avian reovirus (ARV) is diagnostically important protein for development of an ARV-specific enzyme-linked immunosorbent assay (ELISA) and for which production of an antigenic recombinant σB protein in abundance is a prerequisite. In the present study, we successfully employed the prokaryotic system for expression of antigenic σB protein of ARV.

Tomato leaf curl virus (ToLCV) is a major Geminivirus which cause serious loss to tomato production in tropical and subtropical regions of the world. Hence, considered as major constraint to tomato cultivation. In the present study ToLCV coat protein gene was cloned and expressed using recombinant DNA technology approach. The ToLCV infected tomato leaf samples were collected from tomato fields near Krishi Vigyan Kendra, Dharwad. Further, the total DNA from ToLCV infected tomato leaf sample was isolated by following CTAB protocol.

Plasmin is a serine protease that plays a critical role in fibrinolysis, which is a process that prevents blood clots from growing and becoming problematic. Recombinant human microplasminogen (rhμPlg) is a derivative of plasmin that solely consists of the catalytic domain of human plasmin and lacks the five kringle domains found in the native protein.

Human tissue plasminogen activator (tPA) belongs to the serine protease family. It converts plasminogen into plasmin and is used clinically to treat thrombosis. Human tPA is composed of 527 amino acids residues and contains 17 disulfide bonds. Escherichia coli has been used only rarely for the efficient production of recombinant tPA.

A superior Green Fluorescent Protein (GFP) mutant, known as superfolder GFP (sfGFP), is more soluble, faster folding, and is the brightest of the known GFP mutants. This study aimed to create a codon-adapted sfGFP tag (TtsfGFP) for simultaneous protein localization and affinity purification in Tetrahymena thermophila.
