Electrostatics affect virtually all aspects of protein structure and activity and are particularly important in proteins whose primary function is to stabilize charge. Here we introduce a fluorescent ...
Team Develops ‘Cool’ New Method for Probing How Molecules Fold
Cool New Method Molecules Fold
2014/12/30
Using the new system, researchers can force a sample of molecules to unfold and refold by boosting and then dropping the temperature, so quickly that even some of the fastest molecular folding events ...
A new strategy for RNA structure probing in vivo: Targeting methylation small nucleolar RNPs to new sites in ribosomal RNA
Eukaryotic ribosomal RNA nucleotide RNA proteins DNA methylation
2014/12/11
Eukaryotic ribosomal RNAs (rRNAs) contain scores of 2′-O-methylated nucleotides that are formed by a large family of small RNA:protein machines called snoRNPs. The snoRNPs contain a small nucleolar RN...
Probing The Regulation Of Vasculogenic Mimicry In Glioblastoma: Implications For Treatment In Patients

2014/12/10
Glioblastoma, previously known as Glioblastoma Multiforme (GBM), is a highly angiogenic tumor and is defined pathologically by its ability to create microvascular proliferations. Patients with gliobla...
Probing the Peptidyl Transferase Center of Ribosomes Containing Mutant 23S rRNA with Photoreactive tRNA
ribosome peptidyl transferase center photoreactive crosslinking tRNA 23S rRNA translation
2014/12/9
There is strong crystallographic evidence that the 23S rRNA is the only catalytic entity in the peptidyl transferase center. Various mechanisms for the catalysis of peptidyl transfer have been propose...
Probing for Conformational Changes in the Repair Enzyme Mfd Using Mutant Protein Constructs
