Display the word mapDisplay the reaction diagram Show all sequences 2.3.2.12Mg2+ the ribosomal peptidyl transferase center is supported by a framework of magnesium microclusters. Common features of Mg2+-microclusters include two paired Mg2+ ions that are chelated by a common bridging phosphate group in the form Mg2+(a)-(O1P-PO2P)-Mg2+(b). This bridging phosphate is part of a 10-membered chelation ring in the form Mg2+(a)-(OP-P-O5'-C5'-C4'-C3'-O3'-P-OP)-Mg2+(a). The two phosphate groups of this 10-membered ring are contributed by adjacent residues along the RNA backbone. Both Mg2+ ions are octahedrally coordinated, but are substantially dehydrated by interactions with additional RNA phosphate groups. The Mg2+-microclusters in the large subunit appear to be highly conserved over evolution 700504
