Proteins are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.

Basic Rules of Protein Folding
out of 5 stars
31 Dec 2008 | | Contributor(s):: Seth Lichter
How are proteins made? Inside cells, messenger RNA first instructs the ribosomes as to the order which amino acids should be joined together. Linked together and released from the ribosome, the protein is not functional. It now needs to fold into a precise three-dimensional shape. There are no...
Cataract, Myopathy and Keratitis: Possible use of Nanoparticles
16 Sep 2008 | | Contributor(s):: Ch. Mohan Rao
Small heat shock proteins are critical for several cellular functions. Failure of heat shock proteins, thus, can cause compromised cellular activity leading to disease. Fungal Keratitis is an eye dieses that can be treated with anti fungal drugs. Availability of the drug at the site of action is...
Self-association of peptides and proteins: Retrospect and prospects
30 Jul 2008 | | Contributor(s):: R. Nagaraj
The ability of peptides and proteins to form aggregates was known from the dawn of protein and peptide chemistry! It was often considered a nuisance and attention was directed towards disaggregating them to ensure dissolution particularly in aqueous solution. X-ray crystallography has indicated...
Nanobiotechnology – a different perspective
22 Jul 2008 | | Contributor(s):: Murali Sastry
The study of the synthesis, exotic properties, assembly/packaging and potential commercial application of nanomaterials is an extremely important topic of research that is expected to have far-reaching global impact. The focus of my talk will be on an emerging branch of nanotechnology that...
Ionic Selectivity in Channels: complex biology created by the balance of simple physics
05 Jun 2008 | | Contributor(s):: Bob Eisenberg
An important class of biological molecules—proteins called ionic channels—conduct ions (like Na+ , K+ , Ca2+ , and Cl− ) through a narrow tunnel of fixed charge (‘doping’). Ionic channels control the movement of electric charge and current across biological membranes and so play a role in...

Functionalized Nanomaterials at the Interface of Biology and Technology
24 Apr 2008 | | Contributor(s):: Dean Ho, National Center for Learning & Teaching in Nanosca
Nanomaterials, such as block copolymeric membranes and nanodiamonds, can be engineered for a broad range of applications in energy and medicine. This presentation will highlight the relevance of these materials as foundations for device fabrication across the spectrum of biology and technology....
Modeling (Semi) Unstructured Proteins
26 Mar 2008 | | Contributor(s):: Michael Colvin
The past century has seen tremendous progress in determining the biochemical and biophysical processes that constitute life. One exciting consequence of this understanding is the possibility of developing mathematical models of biological function that are accurate and even predictive. My...
Combining New Experimental and Informatic Tools for Protein Investigation and Engineering
09 Jan 2008 | | Contributor(s):: Alan Friedman
The stability and activity of proteins is dependent on both the correct functioning and placement of individual amino acids and their interactions. Great attention has been paid to critical individual residues (generally revealed by their location in the active site and their conservation among...
SPMW Single molecule recognition atomic force microscopy
05 Jan 2007 |
In molecular recognition force microscopy (MRFM), ligands are covalently attached to atomic force microscopy tips for the molecular recognition of their cognitive receptors on probe surfaces. A ligand-containing tip is approached towards the receptors on the probe surface, which possibly leads...
KIST/PU A bi-functional block copolymer hydrogels and micelles for protein and drug delivery
28 Nov 2007 | | Contributor(s):: Doo Sung Lee
Novel biodegradable & injectable poly(Î²-amino ester)-poly(Îµ-caprolactone)-poly(ethylene glycol)-poly(Îµ-caprolactone)-poly(Î²-amino ester)(PAE-PCL-PEG-PCL-PAE) bi-functional, pH/temperature-sensitive, block copolymer hydrogels were prepared and applied to protein and drug delivery. In this...
KIST/PU Introduction to Global Research Laboratory (GRL) Program: Molecular Imaging and Nanomedicine for Theragnosis using Nano-Bio Materials
23 Oct 2007 | | Contributor(s):: Kui Won Choi
The Global Research Laboratory (GRL) program was initiated by the Korea Foundation for International Cooperation of Science and Technology (KICOS) in 2006. The GRL program has been designed to develop fundamental and original technologies through international collaborative research between...
26 Jun 2007 | | Contributor(s):: David D. Nolte
While single-molecule detection through fluorescence has now become common-place, there has been no analogous single-molecule capability using direct detection approaches such as interferometry. This limitation is slowly yielding to high-speed interferoemtric detection that is pushing the...
From Research to Learning in Chemistry through Visualization and Computation
17 May 2007 | | Contributor(s):: Eric Jakobsson
Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...
Introduction to X-ray Photoelectron Spectroscopy and to XPS Applications
17 May 2007 | | Contributor(s):: Dmitry Zemlyanov
X-ray Photoelectron Spectroscopy (XPS), which is known as Electron Spectroscopy for Chemical Analysis (ESCA), is a powerful research tool for the study of the surface of solids. The technique is widely used for studies of the properties of atoms, molecules, solids, and surfaces. The main success...
SPMW AFM at Video Rate and Beyond
16 May 2007 | | Contributor(s):: Mervyn Miles
The particular advantages that atomic force microscopy (AFM) has over other types of microscopy are well-known, but it has the one major disadvantage of low imaging rates in conventional instruments in which each image requires typically a minute or more to collect. This has two major...
