Modular protein-RNA interactions regulating mRNA metabolism: a role for NMR.
Eur Biophys J. 2011 Apr 7;
Authors: Cukier CD, Ramos A
Here we review the role played by transient interactions between multi-functional proteins and their RNA targets in the regulation of mRNA metabolism, and we describe the important function of NMR spectroscopy in the study of these systems. We place emphasis on a general approach for the study of different features of modular multi-domain recognition that uses well-established NMR techniques and that has provided important advances in the general understanding of post-transcriptional regulation.

Role of aminotransferases in glutamate metabolism of human erythrocytes
Role of aminotransferases in glutamate metabolism of human erythrocytes
Abstract Human erythrocytes require a continual supply of glutamate to support glutathione synthesis, but are unable to transport this amino acid across their cell membrane. Consequently, erythrocytes rely on de novo glutamate biosynthesis from α-ketoglutarate and glutamine to maintain intracellular levels of glutamate. Erythrocytic glutamate biosynthesis is catalyzed by three enzymes, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and glutamine aminohydrolase (GA). Although the presence of these...

Sequence specific DNA binding proteins are thought to adopt distinct conformations when binding to target (cognate) and nontarget (noncognate) sequences. There is both biochemical and crystallographic evidence that this behavior is important in mediating sequence recognition...

Modular proteins contain individual domains that are often connected by flexible, unstructured linkers. Using a model system based on the GB1 domain, we constructed tandem repeat proteins and investigated the rotational diffusion and long-range angular ordering behavior of individual domains by measuring...
