The strongest inactivating effect was demonstrated by iodoacetamide and bromoacetamide. However, the negative contribution of this side activity can be minimized by decreasing the temperature, when the rate of acyl donor conversion by penicillin acylases is still high enough, but the impact of enzyme inactivation becomes less significant. The catalytic activity of penicillin acylase from Alcaligenes faecalis in the conversion of 2-haloacetamides was significantly (5-8 times) higher than that of penicillin acylase from Escherichia coli.</p></abstract><trans-abstract xml:lang="ru"><p>Исследованы возможности использования амидов галоген-замещенных уксусных кислот в качестве ацильных доноров в реакциях, катализируемых пенициллинацилазами. Обнаружена способность соединений этой группы инактивировать ферменты в ходе каталитического превращения. Наиболее сильное инактивирующее действие проявляли йодацетамид и бромацетамид, однако негативное влияние этой побочной активности можно минимизировать при понижении температуры, когда каталитическая активность пенициллинацилаз по отношению к этим ацильным донорам остается достаточно высокой, а вклад инактивации фермента в ходе реакции становится менее значительным. Каталитическая активность пенициллинацилазы из Alcaligenes faecalis по отношению к 2-галогенацетамидам существенно (в 5-8 раз) превышала активность пенициллинацилазы из Escherichia coli.</p></trans-abstract><kwd-group xml:lang="en"><kwd>Penicillin acylases</kwd><kwd>substrate specificity</kwd><kwd>2-haloacetamides</kwd><kwd>inactivation during the reaction</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>2-галогенацетамиды</kwd><kwd>инактивация в ходе реакции</kwd><kwd>пенициллинацилазы</kwd><kwd>субстратная специфичность</kwd></kwd-group><funding-group><funding-statement xml:lang="en">Работа выполнена при финансовой поддержке Российского научного фонда (грант № 17-74-10255).</funding-statement><funding-statement xml:lang="ru">This work was supported by the Russian Science Foundation (grant No. 17-74-10255).</funding-statement></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>[1] Svedas V.K., Margolin A.L., Borisov I.L., Berezin I.V. // Enzyme.Microb.Technol. 1980, V.2, P.313-317</mixed-citation></ref><ref id="B2"><label>2.</label><mixed-citation>[2] Gololobov M.Y., Borisov I.L., Svedas V.K. // J.
