Mapping proteins of the 50S subunit from Escherichia coli ribosomes.
Mapping of protein positions in the ribosomal subunits was first achieved for the 30S subunit by means of neutron scattering about 15 years ago. Since the 50S subunit is almost twice as large as the 30S subunit and consists of more proteins, it was difficult to apply classical contrast variation techniques for the localisation of the proteins. Polarisation dependent neutron scattering (spin-con...
متن کاملProteins at the tRNA binding sites of Escherichia coli ribosomes.
p - Nitrophenylcarbamyl - phenylalanyl-tRNA binds to ribosomes in response to poly(U) and reacts with ribosomal proteins via covalent bond formation. Ribosomal proteins of Escherichia coli were characterized by two-dimensional gel electrophoresis and by reaction with specific antibodies. The affinity label is shown to react with the 50S proteins L27, L15, L2, L16, and L14. We therefore conclude...

هدف از انجام این تخقیق بررسی رابطه احتمالی بین سطح مهارت زبان خارجی (foreign language proficiency) و ساختار مهارت زبان خارجی بود. تعداد 314 زبان آموز مونث و مذکر که عمدتا دانشجویان رشته های زبان انگلیسی در سطوح کارشناسی و کارشناسی ارشد بودند در این تحقیق شرکت کردند. از لحاظ سطح مهارت زبان خارجی شرکت کنندگان بسیار با هم متفاوت بودند، (75 نفر سطح پیشرفته، 113 نفر سطح متوسط، 126 سطح مقدماتی). کلا ...

Erythromycin binding to Escherichia coli ribosomes required K+ and Mg2+. Under optimal conditions, the dissociation constant for erythromycin binding to E. coli ribosomes was found to be 1.0 x 108M and 1.4 x 108M at 24 C and 5 C, respectively. One molecule of [I4C Jerythromycin was bound to each 70S ribosome at equilibrium. Binding of erythromycin to ribosomes was rapid and reversible. The spec...
متن کاملAmino Acid Incorporation into Proteins by Escherichia Coli Ribosomes.
Evidence that ribosomes are an important site of protein synthesis has come mainly from experiments with animal cells. It has been shown in vivo that C14 amino acids are incorporated into peptide linkage first in ribosomes, and by addition of cold amino acids, they can be chased to the bulk of the proteins of the cell.1-3 In vitro, they become bound in ribosomal proteins2 or, after their passag...
