Performance improvement of araujiain, a cystein phytoprotease, by immobilization within calcium alginate beads

The effect of immobilization within alginate beads on the performance of araujiain in aqueous and non-aqueous media was studied. Optimum pH and temperature, thermal and pH-stability, kinetic parameters and operational stability were determined. Entrapped

Engineered Substrate for Cyclooxygenase-2: A Pentapeptide Isoconformational to Arachidonic Acid for Managing Inflammation

Beyond the conventional mode of working of anti-inflammatory agents through enzyme inhibition, herein, COX-2 was provided with an alternate substrate. A proline-centered pentapeptide isoconformational to arachidonic acid, which exhibited appreciable selectivity for COX-2, overcoming acetic acid- and formalin-induced pain in rats to almost 80%, was treated as a substrate by the enzyme. Remarkably, COX-2 metabolized the pentapeptide into small fragments consisting mainly of di- and tripeptides that ensured the safe breakdown of the peptide under in vivo conditions. The kinetic parameter Kcat/Km for COX-2-mediated metabolism of the peptide (6.3 × 105 M-1 s-1) was quite similar to 9.5 × 105 M-1 s-1 for arachidonic acid. Evidenced by the molecular dynamic studies and the use of Y385F COX-2, it was observed that the breakage of the pentapeptide has probably been taken place through H-bond activation of the peptide bond by the side chains of Y385 and S530.

Peptiligase, an Enzyme for Efficient Chemoenzymatic Peptide Synthesis and Cyclization in Water

We describe a novel, organic cosolvent-stable and cation-independent engineered enzyme for peptide coupling reactions. The enzyme is a variant of a stable calcium-independent mutant of subtilisin BPN′, with the catalytic Ser212 mutated to Cys and Pro216 converted to Ala. The enzyme, called peptiligase, catalyzes exceptionally efficient peptide coupling in water with a surprisingly high synthesis over hydrolysis (S/H) ratio. The S/H ratio of the peptide ligation reaction is correlated to the length of the peptide substrate and proved to be >100 for the synthesis of a 13-mer peptide, which corresponds to >99% conversion to the ligated peptide product and 1% hydrolytic side-reaction. Furthermore, peptiligase does not require a particular recognition motif resulting in a broadly applicable and traceless peptide ligation technology. Peptiligase is very robust, easy to produce in Bacillus subtilis, and its purification is straightforward. It shows good activity and stability in the presence of organic cosolvents and chelating or denaturing agents, enabling the ligation of poorly soluble (hydrophobic) or folded peptides. This enzyme could be useful for the (industrial) synthesis of diverse (pharmaceutical) peptides. In addition, peptiligase is able to efficiently catalyze head-to-tail peptide cyclization reactions.
