Они применяются в медицинской практике для терапии воспалений, онкологии и туберкулеза. Бактерии родов Salmonella, Pseudomonas и Acinetobacter устойчивы к токсическому действию MSX и MSO благодаря активности L-метионин сульфоксимин ацетилтрансфераз (MSX-NAT). В данной работе проведен анализ MSX-NAT различных видов рода Enterobacter из группы ESKAPE патогенов. Анализ множественного выравнивания ферментов выявил высокий процент идентичности их последовательностей, несмотря на разнообразие длин их полипептидных цепей, а также дополнительные уникальные вставки в N-концевой области белков, функции которых пока не установлены.</p></abstract><trans-abstract xml:lang="en"><p>L-methionine derivatives (L-methionine sulfoximine (MSX) and L-methionine sulfone (MSO)) are  inhibitors of L-glutamine synthetase, which explains their toxic effect on cells. These derivatives are  used in medical practice for treating inflammation, tuberculosis, and oncological diseases. Bacteria of the Salmonella, Pseudomonas, and Acinetobacter genera are resistant to the toxic effect of MSX and MSO due to the activity of L-methionine sulfoximine acetyltransferases (MSX-NAT). In this work, MSX-NAT from various Enterobacter species from the ESKAPE group of pathogens was analyzed. An  analysis of multiple enzyme alignments revealed a high percentage of their sequence identity, despite the diversity of their polypeptide chain lengths. In addition, unique insertions in the N-terminal region of the proteins were found, the functions of which remain to be clarified.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ESKAPE</kwd><kwd>GNAT-ацетилтрансферазы</kwd><kwd>L-метионин сульфоксимин</kwd><kwd>глутамин синтетаза</kwd><kwd>Enterobacter spp.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ESKAPE</kwd><kwd>GNAT-acetyltransferase</kwd><kwd>L-methionine sulfoximine</kwd><kwd>glutamine synthetase</kwd><kwd>Enterobacter spp.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено при финансовой поддержке Российского научного фонда, грант № 23-24-00478.</funding-statement><funding-statement xml:lang="en">research was funded by a grant from the Russian Science Foundation No. 23-24-00478.</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">Berlicki L.
