Особый интерес представляют микроорганизмы, паразитирующие на человеке и домашних животных. В работе был проведен биоинформатический анализ геномов 62 штаммов бактерий, принадлежащих к роду Mycoplasma. Показано, что эффективность трансляции генов у этих организмов зависит от количества потенциальных вторичных структур в них и не зависит от кодонного состава. Обнаружены виды с пониженным содержанием локальных инвертированных повторов в генах. Анализ филогении показал возможную связь этой особенности со средой обитания данных организмов. Обнаружена не свойственная остальным микоплазмам высокая концентрация локальных инвертированных повторов в районе старт-кодона трансляции в генах M. haemofelis.</p></abstract><trans-abstract xml:lang="en"><p>Evaluation of gene expression efficiency in different organisms is a vital task of modern biology. Microorganisms that feed on humans and pets are particularly interesting. In this work, bioinformatical analysis of 62 Mycoplasma strains is performed. It has been shown that translation efficiency in these organisms depends on the number of potential secondary structures in genes and does not depend on codon compositions. Several species with low concentrations of local inverted repeats in genes have been found. Phylogenetic analysis shows that this feature may be associated with their environment. High concentrations of local inverted repeats, not typical of other Mycoplasma species, have been found in the translation start regions of M. haemofelis genes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Mycoplasma</kwd><kwd>частоты кодонов</kwd><kwd>вторичные структуры</kwd><kwd>эффективность трансляции</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Mycoplasma</kwd><kwd>codon frequencies</kwd><kwd>secondary structures</kwd><kwd>translation efficiency</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>программы Президиума РАН «Молекулярная и клеточная биология» (проект 6.6) и «Происхождение биосферы и эволюция гео-биологических систем» (№ 15); грант НШ-5278.2012.4 и грант РФФИ № 13-04-0062013</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">Лихошвай В.А., Матушкин Ю.Г.
