Unit Testing Template For Etli
Bacterial l-asparaginase has been a universal component of therapies for childhood acute lymphoblastic leukemia since the 1970s. Two principal enzymes derived from Escherichia coli and Erwinia chrysanthemi are the only options clinically approved to date. We recently reported a study of recombinant l-asparaginase (AnsA) from Rhizobium etli and described an increasing type of AnsA family members. Sequence analysis revealed four conserved motifs with notable differences with respect to the conserved regions of amino acid sequences of type I and type II l-asparaginases, particularly in comparison with therapeutic enzymes from E. These differences suggested a distinct immunological specificity. Free Download Program Orenco Pump Select Program Bmw on this page. Here, we report an in silico analysis that revealed immunogenic determinants of AnsA. Also, we used an extensive approach to compare the crystal structures of E.

Chrysantemi asparaginases with a computational model of AnsA and identified immunogenic epitopes. A three-dimensional model of AsnA revealed, as expected based on sequence dissimilarities, completely different folding and different immunogenic epitopes. This approach could be very useful in transcending the problem of immunogenicity in two major ways: by chemical modifications of epitopes to reduce drug immunogenicity, and by site-directed mutagenesis of amino acid residues to diminish immunogenicity without reduction of enzymatic activity. Introduction The last two decades have been characterized by the emergence of a great number of proteins as potential drug candidates to treat diseases in patients with various cancers, or as treatments for heart attacks, strokes, cystic fibrosis, Gaucher’s disease, diabetes, anemia, hemophilia and inflammation. These therapeutic proteins are extracted from plants, microbes or human cells or are engineered in the laboratory for pharmaceutical use. Adair F, Ozanne D.

In conjunction, changes introduced into a molecule avoid rare errors in gene transcription or translation, and protein preparations do not contain residual amounts of harsh chemicals used in the purification process. Engineering of therapeutic proteins production in Escherichia coli. Curr Pharm Biotechnol 2011; 12: 268 - 74; 10.213; PMID: 21050165,, From a therapeutic perspective, proteins offer the distinct advantage of specific mechanisms of action and high potency. Despite these advantages, biotech products must overcome the hurdles posed by their high molecular weights, short half-lives, instability and immunogenicity. Several strategies have been evaluated in an effort to improve the current limitations of therapeutic peptides and proteins in the creation of so-called “second-generation” protein therapeutics.
