Методом генетической инженерии нами был получен химерный фермент на основе ПМО Thielavia terrestris, к С-концу которого присоединен через пептидный линкер целлюлозосвязывающий модуль (ЦСМ) от целлобиогидролазы I Penicillium verruculosum. Химерная ПМО обладала более высокой (на 24 %) активностью по отношению к аморфной целлюлозе и расширенной субстратной специфичностью по сравнению с исходной ПМО. В результате присоединения ЦСМ химерная ПМО приобрела способность расщеплять помимо целлюлозы и β-глюкана ксилан и карбоксиметилцеллюлозу, а ее активность по отношению к ксилоглюкану возросла на порядок. При замене 10 % высокоактивного целлюлазного препарата hBGL2, продуцируемого P. verruculosum, на химерную ПМО при сохранении общей дозировки ферментов по концентрации белка выход сахаров при гидролизе микрокристаллической целлюлозы и измельченной осиновой древесины увеличился на 24 и 47 % соответственно, причем при деструкции древесины максимальный выход сахаров был достигнут через 24 ч реакции в отличие от гидролиза указанным препаратом без добавки ПМО, длящегося 48 ч.</p></abstract><trans-abstract xml:lang="en"><p>Polysaccharide monooxygenases (PMO) was discovered several years ago in the composition of cellulase complexes to improve their saccharification capacity considerably. Methods of genetic engineering were used for creation of a chimeric PMO Thielavia terrestris based on enzyme with a cellulose-binding module (CBM) from cellobiohydrolase I Penicillium verruculosum attached through a peptide linker to the C-end. The chimeric PMO was more active (by 24 %) to amorphous cellulose and wider substrate specific than the initial PMO. With the attachedCBM, the chimeric PMO became capable of cleaving not only cellulose and β-glucane, but also xylane and CMC, while its activity to xyloglucane increased by an order of magnitude. In hydrolysis of MCC and aspen sawdust, when the chimeric PMO was substituted for 10 % of the highly active cellulase preparation hBGL2 produced by P. verruculosum at the retained total enzyme dosage with respect to the protein concentration, the yield of sugars increased by 24 and 47 %, respectively, the maximal sugar yield being reached in 24 hours of the reaction against 48 hours in the presence of the PMO-free preparation.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>химерная полисахаридмонооксигеназа</kwd><kwd>целлюлазный комплекс</kwd><kwd>биоконверсия растительного сырья</kwd><kwd>Thielavia terrestris</kwd><kwd>Penicillium verruculosum</kwd></kwd-group><kwd-group xml:lang="en"><kwd>chimeric polysaccharide monooxygenases</kwd><kwd>cellulase complex</kwd><kwd>bioconversion of plant materials</kwd><kwd>Thielavia terrestris</kwd><kwd>Penicillium verruculosum</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Margeot A., Hahn-Hagerdal B., Edlund M., Slade R., Monot F. // Current Opinion in Biotechnology. 2009.
