rotein structure prediction from a sequence is one of the high focus problems for researchers.This is a very useful application of bioinformatics as the experimental techniques like X-ray crystallography are time consuming.The fundamental issue is how can we predict the 3-D shape of a protein from its amino acid sequence. In this paper we will learn how to predict protein structure and function...

Binding of the Tetrahymena ribozyme's oligonucleotide substrate (S) involves P1 duplex formation with the ribozyme's internal guide sequence (IGS) to give an open complex, followed by docking of the P1 duplex into the catalytic core via tertiary interactions to give a closed complex. The overall binding energies provided by 2' OH groups on S and IGS have been measured previously. To obtain the ...

A new coupling protocol has been developed that allows the union of vinyl sulfones with photoredox-generated α-amino radicals to provide allylic amines of broad diversity. Direct C-H vinylations of N-aryl tertiary amines, as well as decarboxylative vinylations of N-Boc α-amino acids, proceed in high yield and with excellent olefin geometry control. The utility of this new allyl amine forming re...

MOTIVATION Is protein secondary structure primarily determined by local interactions between residues closely spaced along the amino acid backbone or by non-local tertiary interactions? To answer this question, we measure the entropy densities of primary and secondary structure sequences, and the local inter-sequence mutual information density. RESULTS We find that the important inter-sequenc...
