Proteinase sensitivity of bacteriophage lambda tail proteins gpJ and pH in complexes with the lambda receptor.
Previous studies have shown that bacteriophage lambda initially binds to liposomes bearing its receptor protein by the tip of the tail fiber (type 1 complex). It then associates more directly so that the hollow tail tube is in direct contact with the membrane (type 2 complex). DNA can be injected across the lipid bilayer into the liposome from type 2 complexes. We show here that gpJ, the tail f...

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 اولStructure determination of the head-tail connector of bacteriophage phi29.
The head-tail connector of bacteriophage phi29 is composed of 12 36 kDa subunits with 12-fold symmetry. It is the central component of a rotary motor that packages the genomic dsDNA into preformed proheads. This motor consists of the head-tail connector, surrounded by a phi29-encoded, 174-base, RNA and a viral ATPase protein, both of which have fivefold symmetry in three-dimensional cryo-electr...
متن کاملMass distribution of a probable tail-length-determining protein in bacteriophage T4.
Analysis of dark-field scanning transmission electron micrographs of unstained freeze-dried specimens established that the interior of the intact bacteriophage T4 tail tube contains extra density that is missing in tubes artificially emptied by treatment with 3 M guanidine hydrochloride. The mass of the tail tube is 3.1 X 10(6) daltons, and the central channel is 3.2 nm in diameter. Quantitativ...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
