What is X-ray crystallography?

Feb 28, 2020 ... Researchers at Northwestern Engineering have developed a system that can rapidly create cell-free ribosomes in a test tube, then select the ribosome that can ... The tour is designed for users with at least a general familiarity with translation and the ribosome, such as students who have taken general biology ... In eukaryotes, ribosomes get their orders for protein synthesis from the nucleus, where portions of DNA (genes) are transcribed to make messenger RNAs (mRNAs). Jan 19, 2022 ... Aging impairs the ability of ribosomes to efficiently synthesize proteins and leads to protein misfolding and aggregation, which disrupts cellular health. Abstract. The ribosome is a large multifunctional complex composed of both RNA and proteins. Biophysical methods are yielding low-resolution structures of the ... ... ribosome concentration cause a huge fractional change in ribosome inactivity. ... ribosomes are typically highly abundant and thus costly, and the required ... The ribosome that is synthesizing the protein is directly attached to the ER membrane. These membrane-bound ribosomes coat the surface of the ER, creating ... It has recently become clear that ribosomes are much more heterogeneous than previously thought, with diversity arising from rRNA sequence and modifications. As calculated in the fourth column of the table, and schematically in Figure 1, at a fast doubling time of 24 minutes the 72,000 ribosomes per cell represent ... Apr 29, 2024 ... ... they do. By investigating differences among ribosomes, we may be opening the door to drugs that target specific pathogenic bacteria […]
