Проведён скрининг активности полученных белков против различных патогенных микроорганизмов. Показано, что рибонуклеозидгидролаза С (RihC) и цистеинсинтаза А (CysK) обладают активностью против биоплёнок некоторых микроорганизмов группы ESKAPE. Для RihC также показан синергизм действия с некоторыми антибиотиками. Протеаза М23 в некоторых случаях показала собственную активность против патогенных микроорганизмов, а также синергизм с целым рядом антибактериальных препаратов: меропенемом, азтреонамом, цефтазидимом.</p></abstract><trans-abstract xml:lang="en"><p>Recombinant proteins from lactobacilli were obtained in purified soluble form. These proteins were subsequently screened for activity against a range of pathogenic microorganisms. Ribonucleoside hydrolase C (RihC) and cysteine synthase A (CysK) were shown to exhibit activity against biofilms of certain ESKAPE microorganisms. RihC also exhibited synergistic activity with certain antibiotics. In some cases, protease M23 has demonstrated intrinsic activity against pathogenic microorganisms, as well as synergism with a number of antibacterial drugs — meropenem, aztreonam, and ceftazidime.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>рекомбинантные белки</kwd><kwd>антимикробная активность</kwd><kwd>лактобактерии</kwd><kwd>действие против биоплёнок</kwd><kwd>протеаза М23 из лактобактерий</kwd></kwd-group><kwd-group xml:lang="en"><kwd>recombinant proteins</kwd><kwd>antimicrobial activity</kwd><kwd>lactobacilli</kwd><kwd>activity against biofilms</kwd><kwd>protease M23 from</kwd><kwd>lactobacilli</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при частичной поддержке гранта РНФ № 23-64-10029, https://rscf.ru/project/23-64-10029/</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Справочник по антимикробной терапии.
