Structures of triacetyloleandomycin and mycalamide A bind to the large ribosomal subunit of Haloarcula marismortui.
Structures have been obtained for the complexes that triacetyloleandomycin and mycalamide A form with the large ribosomal subunit of Haloarcula marismortui. Triacetyloleandomycin binds in the nascent peptide tunnel and inhibits the activity of ribosomes by blocking the growth of the nascent peptide chain. Mycalamide A binds to the E site and inhibits protein synthesis by occupying the space nor...

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...

15 صفحه اولThe structures of antibiotics bound to the E site region of the 50 S ribosomal subunit of Haloarcula marismortui: 13-deoxytedanolide and girodazole.
Crystal structures of the 50 S ribosomal subunit from Haloarcula marismortui complexed with two antibiotics have identified new sites at which antibiotics interact with the ribosome and inhibit protein synthesis. 13-Deoxytedanolide binds to the E site of the 50 S subunit at the same location as the CCA of tRNA, and thus appears to inhibit protein synthesis by competing with deacylated tRNAs for...
متن کاملCharacterization and preliminary attempts for derivatization of crystals of large ribosomal subunits from Haloarcula marismortui diffracting to 3 A resolution.
An improved form of crystals of large (50 S) ribosomal subunits from Haloarcula marismortui, formally named Halobacterium marismortui, diffracting to 3 A resolution, has been obtained by the addition of 1 mM-Cd2+ to the crystallization medium, which contained more than 1.9 M of other salts. The improved crystals, grown from functionally active particles to an average size of 0.3 mm x 0.3 mm x 0...
