Comparison of Two Methods for Assaying Reducing Sugars in the Determination of Carbohydrase Activities
TL;DR: The Nelson-Somogyi and 3,5-dinitrosalicylic acid assays for reducing sugars are widely used in measurements of carbohydrase activities against different polysaccharides, and reasons for preferential use of the NS assay for measuring activities of carbohydrases other than cellulases are discussed.
Journal ArticleDOI
Purification and characterization of two forms of the homologously expressed lytic polysaccharide monooxygenase (PvLPMO9A) from Penicillium verruculosum
M. V. Semenova,Alexander V. Gusakov,Vadim D. Telitsin,Aleksandra M. Rozhkova,Aleksandra M. Rozhkova,Elena G. Kondratyeva,Arkady P. Sinitsyn,Arkady P. Sinitsyn +7 more
TL;DR: These data show that both active site copper and C-terminal domain present in the PvLPMO9A-hm protect the enzyme from thermal unfolding, while the stabilizing effect of metal is much less pronounced in the truncated Pv lpmo1-lm form.
Journal ArticleDOI
Properties of recombinant endo-β-1,6-glucanase from Trichoderma harzianum and its application in the pustulan hydrolysis.
P.V. Volkov,E. A. Rubtsova,Alexandra M. Rozhkova,O. A. Sinitsyna,Ivan N. Zorov,Elena G. Kondratyeva,Arkady P. Sinitsyn +6 more
TL;DR: The gene encoding Trichoderma harzianum fungus pustulanase was cloned and heterologously expressed by the highly productive Penicillium verruculosum fungus and reaction product analysis by HPLC clearly indicated that ThBGL1.6 has an endo-hydrolytic mode of action against pustULan as specific substrate.
Journal ArticleDOI
Seasonal variations in serum vitamin D levels in children and adults with various diseases
Nuriniso Dzhumaevna Odinaeva,Elena G. Kondratyeva,E.V. Loshkova,I.M. Osmanov,A.I. Khavkin,Irina N. Zakharova,Yu.F. Shubina,E. Pasnova,Yu. B. Ponomarenko +8 more
TL;DR: Vitamin D deficiency was observed throughout the year, which did not correspond to increasing daylight hours, and in patients with autoimmune diseases and chronic kidney disease, the lowest serum 25(OH)D levels were recorded in winter and spring.
