Advanced light source reveals secrets of ribosome structure
... like the ALS,obtaining detailed information about macromolecular
structures such as ribosomeswas an almost insurmountable challenge. Yet this information is essential forunderstanding the mechanism by which these critical organelles function. Whileother research groups have obtained high-resolution images of indiv...
Reversible Process For Forming Supramolecular Polymers Could Be The Basis Of Fibers, Molecular Transport Mechanisms
... in layers on a three-armed ammonium salt toform a macromolecular
aggregate. The huge supramolecule takes three days to form. Again the process was firstdescribed in Angewandte Chemie. (Angew. Chem. Int. Ed. 1998, 37, No. 23:"Dendritic Pseudorotaxanes," by Yamaguchi, Lesley M. Hamilton, and Gibson.)The result is "...
NYU Researchers Develop Simple, Predictable And Precise Technique For Arranging
DNA Molecules Into Two-Dimensional Crystals
...ion atSUNY/Albany, where his frustrations with the macromolecular
crystallizationexperiment led him one day to the campus pub. There, he realized that thesimilarity between 6-arm DNA branched junctions and the periodic array of flyingfish in Escher's 'Depth' might lead to the rational approach to crystallizationde...
Feature: Biomaterials Are Transforming Medicine
...in hydrophobic polymers made itpossible to deliver macromolecular
drugs like albumin into the body and at acontrolled rate over a period of time. Since then, biomaterials have enabled the slow release of ever-largerbioengineered proteins into the body, with release times ranging from one day tomore than th...
DFG To Set Up 14 New Collaborative Research Centres
...esearch. Thecollaborative research centre "Complex macromolecular
and hybrid systems in internaland external fields " to be established at Bayreuth University plans to organise andcharacterise such nano-structures on different scales of length by means of molecularinteraction as well as mechanical, electric and mag...
Three-Dimensional Structure Of Human Lung Tryptase Determined, An Enzyme Involved In Allergic Asthma
...ds an oval central pore, restricting access for macromolecular
substrates and inhibitors. Heparin chains could stabilize the complex by binding to an elongated patch of positively charged residues spanning two adjacent monomers. This unique tetrameric architecture explains many of tryptase's distinct...
Insights Into The Proteasome - A Fascinating Macromolecular Machine For Protein Degradation
...n the proteasome as one of the most fascinating macromolecular
machines of the cell. The authors report on own data and review the current status of the topic. Protein degradation is a necessity but also a hazard. It must be subject to precise spatial and temporal control to prevent that prot...
