abstract：:Major progress in the study of RNase P has resulted from crystallography of bacterial catalytic subunits and the discovery of catalytic activity in eukaryotes. Several new substrates have also been identified, primarily in bacteria but also in yeast. Our current world should be called the "RNA-protein world" rather th...

abstract：:Cellular heterogeneity and stochastic fluctuation play key roles in biological processes. Single molecule approaches have the key advantage of avoiding ensemble averaging, allowing the observation of transient intermediates and heterogeneity (both static and dynamic). Thus they have revolutionised the way many biologi...

abstract：:Protein tyrosine phosphatases (PTPs) constitute a large family of enzymes that play key roles in cell signaling. Deregulation of PTP activity results in aberrant tyrosine phosphorylation, which has been linked to the etiology of several human diseases, including cancer. Since phosphate removal by the PTPs can both enh...
