Molecular modeling of enzyme interactions with the N- and C-terminal tetrapeptide fragments of growing peptidoglycan chains has been performed for the first time and has allowed us to highlight the peculiarities of their binding at the formation of 3-3 cross-linkages, as well as to build a full-atom model of L,D-transpeptidase 2 for the screening and optimizing of inhibitors’ structures.</p></abstract><trans-abstract xml:lang="ru"><p>L,D-транспептидаза 2-го типа из Mycobacterium tuberculosis играет ключевую роль в формировании неклассических 3-3 поперечных сшивок пептидогликана в клеточной стенке патогена, обуславливая его устойчивость к широкому спектру антибиотиков пенициллинового ряда. Впервые проведенное исследование взаимодействия фермента с тетрапептидным фрагментом пептидогликана клеточной стенки при помощи методов молекулярного моделирования позволило выявить особенности связывания N- и C-концевых фрагментов растущей цепи пептидогликана этим ферментом при образовании 3-3 поперечных сшивок и построить полноатомную модель LdtMt2 для скрининга и оптимизации структуры ингибиторов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>L,D-transpeptidase</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>catalytic mechanism</kwd><kwd>molecular docking</kwd><kwd>molecular dynamics simulations</kwd><kwd>inhibitors</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>L,D-транспептидаза</kwd><kwd>Mycobacterium tuberculosis</kwd><kwd>ингибиторы</kwd><kwd>каталитический механизм</kwd><kwd>молекулярный докинг</kwd><kwd>молекулярная динамика</kwd></kwd-group><funding-group><funding-statement xml:lang="en">This work was financially supported by the Russian Science Foundation (grant No. 15-14-00069).</funding-statement><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 15-14-00069).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] // WHO.
