При этом имеет значение не только концентрация токсичных и эссенциальных металлов в биологических жидкостях, но и их способность взаимодействовать с белками и ферментами, определяющая активность последних. Целью работы было сравнить возможности связывания различных ионов металлов с белками сыворотки крови человека. Изучение реакций иммобилизованных ионов металлов (Cu2+, Zn2+, Mn2+, Ca2+, Fe3+, Mg2+, Hg+, Cd2+, Pb2+, Cr3+, Co2+, Ag+, Bi2+, Ba2+, Sr2+) с белками крови, а также с высокоочищенным металлопротеином крови (альфа-2-макроглобулин, а2-МГ) проводили методом перекрестного иммуноэлектрофореза с адсорбцией in situ во втором направлении. Показано, что в реакциях in vitro ионы Hg+, Cu2+, Zn2+, Cd2+ активнее других взаимодействуют с металлопротеинами (в частности с а2-МГ) и со многими другими белками крови человека. Продемонстрировано, что а2-МГ взаимодействует не только с ионами Zn2+ и Cd2+, как описано ранее, но и с Ca2+, Mg2+, Fe3+, Mn2+, Pb2+, Sr2, Ag+. Выявлено взаимодействие ряда ионов металлов, в том числе высокотоксичных, с белками крови, не являющимися металлопротеинами. Результаты подтверждают принципиальную возможность активного участия дисбаланса ионов металлов в обменных нарушениях через воздействие на регуляторные и транспортные белки организма, что требует дальнейшего изучения.</p></abstract><trans-abstract xml:lang="en"><p>Homeostasis of metals plays an important role in functioning of the body. Not only the concentrations of toxic and essential metals in bodily fluids, but also their ability of interaction with proteins and enzymes defining the enzyme activity, are important. The study was aimed to compare the possibilities of binding interactions between various metal ions and human serum proteins. Chemical reactions between the immobilized metal ions (Cu2+, Zn2+, Mn2+, Ca2+, Fe3+, Mg2+, Hg+, Cd2+, Pb2+, Cr3+, Co2+, Ag+, Bi2+, Ba2+, Sr2+) and the serum proteins or highly purified blood metalloprotein (alpha-2-macroglobulin, α2M) were assessed by the crossed immunoelectrophoresis with in situ adsorption in the second dimension. It has been shown that Hg+, Cu2+, Zn2+, Cd2+ ions more actively interact with metalloproteins (particularly, with α2M) and many other human blood proteins in in vitro reactions than other ions. We have demonstrated that α2M interacts not only with Zn2+ and Cd2+ ions, as earlier reported, but also with Ca2+, Mg2+, Fe3+, Mn2+, Pb2+, Sr2, Ag+. Interaction of a number of metal ions, including highly toxic ones, with blood proteins that are not metalloproteins has been revealed. The findings confirm the fundamental possibility of the metal ion imbalance active involvement in metabolic disorders via effects on the body's regulatory and transport proteins, which requires further investigation</p><p> </p></trans-abstract><kwd-group xml:lang="ru"><kwd>ионы металлов</kwd><kwd>металлопротеины</kwd><kwd>альфа-2-макроглобулин</kwd><kwd>иммуноэлектрофорез</kwd><kwd>интоксикация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>metal ions</kwd><kwd>metalloproteins</kwd><kwd>alpha-2-macroglobulin</kwd><kwd>immunoelectrophoresis</kwd><kwd>intoxication</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Wang F, Chmil C, Pierce F, Ganapathy K, Gump B, MacKenzie J, Mechref Y, Bendinskas K.
