We investigated the potential utility of a recombinant E. coli that expresses the human metallothionein II gene as a fusion protein with beta-galactosidase as a heavy metal biosorbent. E. coli cells expressing the metallothionein fusion demonstrated enhanced binding of Cd2+ compared to cells that lack the metallothionein. It was shown that the metallothionein fusion was capable of efficiently r...

YOR068c, termed VAM10 (altered vacuole morphology), lies within the VPS5 gene on the opposite DNA strand. VAM10 deletion causes vacuole fragmentation in vivo. The in vitro fusion of purified yeast vacuoles is stimulated by recombinant Vam10p and blocked by antibody to Vam10p. Vam10p acts early in the priming stage of fusion, independent of Sec18p. After priming, recombinant Vam10p will not stim...

BACKGROUND Expression of recombinant proteins in green algal chloroplast holds substantial promise as a platform for the production of human therapeutic proteins. A number of proteins have been expressed in the chloroplast of Chlamydomonas reinhardtii, including complex mammalian proteins, but many of these proteins accumulate to significantly lower levels than do endogenous chloroplast protein...

Sec1 proteins are critical players in membrane trafficking, yet their precise role remains unknown. We have examined the role of Sec1p in the regulation of post-Golgi secretion in Saccharomyces cerevisiae. Indirect immunofluorescence shows that endogenous Sec1p is found primarily at the bud neck in newly budded cells and in patches broadly distributed within the plasma membrane in unbudded cell...

background and objectives: toxoplasma gondii is an obligatory intracellular parasite which causes severe diseases in the fetus of pregnant women and immunocopmromised patients. serological tests based on recombinant protein are one of the main diagnosis methods for the detection of specific antibodies in serum samples. dense granule antigenic proteins derived from t. gondii (tggras) are potenti...

newcastle is a significant avian disease continuing to cause considerable loss. developments in genetic engineering have led to plant-based platforms for human and animal vaccine production. recombinant vaccine production in hairy root systems have several advantages over stable expression in whole plants, including high growth rates, ready genetic manipulations, high levels of recombinant prot...

background: parasite proteases have important roles in cleavage of host proteins during the invasion of host tissues and participate in the parasite’s evasion from the host’s immune response. the aim of the present study was to estimate a metalloproteinase properties of taenia solium metacestode (tsmp) during host-parasite interactions, and evaluate its potential as a serodiagnostic antigen for...

A cancer immunotherapy strategy is described herein that combines the advantage of the well established tumor targeting capabilities of high-affinity recombinant fragments of Abs with the known efficient, specific, and potent killing ability of CD8 T lymphocytes directed against highly antigenic MHC-peptide complexes. Structurally, it consists of a previously uncharacterized class of recombinan...
