[Abstract] Nedd8 is a small ubiquitin-like protein (9 kDa) covalently attached to a conserved lysine residue of a cullin protein which is part of cullin-RING ligases (CRLs). CRLs are major E3 ligases important for protein ubiquitination in the ubiquitin-proteasome pathway (UPP). The activity of CRLs is regulated ...

[Abstract] GfsA is a fungal β-galactofuranosyltransferase involved in the biosynthesis of O-glycan. To investigate the enzymatic functions of GfsA, we attempted to obtain a recombinant protein of this enzyme from two heterologous host organisms. However, GfsA could not be expressed as a recombinant protein in ...

[Abstract] Transport assays allow the direct kinetic analysis of a specific transporter by measuring apparent Km and Vmax values, and permit the characterization of substrate specificity profiles through competition assays. In this protocol, we describe a rapid and easy method for performing uptake assays in the ...

[Abstract] Western blotting allows for the specific detection of proteins and/or modifications of proteins by an antibody of interest. This protocol utilizes a crude nuclei extraction protocol for Aspergillus nidulans to enrich for histones and other nuclear proteins prior to gel electrophoresis. Post translational ...
