Bis(benzimidazole)amine-based copper complexes, with structural similarities to the active sites of Lytic Polysaccharide Monooxygenase enzymes (LPMOs), were tested for oxidative degradation cellulose. Spectroscopic characterization as well authentication one them, confirm a tetragonal coordination environment 3 nitrogen donors, thioether in axial positions. Aqueous cellulose was achieved CuII c...

Lytic polysaccharide monooxygenases (LPMOs) are recently discovered enzymes that oxidatively deconstruct polysaccharides. LPMOs are fundamental in the effective utilization of these substrates by bacteria and fungi; moreover, the enzymes have significant industrial importance. We report here the activity, spectroscopy and three-dimensional structure of a starch-active LPMO, a representative of ...

A rapid method for assessing the lytic activity of antimicrobial agents against yeast and fungi has been developed. The assay is based on the release of the intracellular enzyme, maltase (alpha-glucosidase). The released maltase activity was measured colorimetrically by the production of p-nitrophenol from p-nitrophenyl-alpha-D-glucopyranoside (PNPG). The lytic activity of different antimicrobi...

Mutanolysin partially purified from the culture filtrate of Streptomyces globisporus 1829 consists of two main lytic enzymes with an isoelectric point near pH 8.5 and 10, respectively, and proteolytic enzyme is associated with the latter lytic enzyme. Mutanolysin exhibited maximal lytic activity at 60 C in the pH range 6.5 to 7.0 and was stable at 50 C in the acid range. N-bromosuccinimide caus...
