Substituted Cysteine Accessibility Method for Topology and Activity Studies of Membrane Enzymes Forming Thioester Acyl Intermediates in Bacteria
[Abstract]  The topology of membrane proteins and enzymes can be determined using various methods including reporter protein fusions and accessibility of cysteine residues to alkylating agents. Here we describe a variation of the substituted cysteine accessibility method to determine membrane topology and activity of enzymes containing an active site cysteine. Membrane topology of proteins can be predicted using different programs and the actual membrane topology can be determined by monitoring the ...

A Protocol to Measure the Extent of Cell-to-cell Movement of RNA Viruses in Planta
[Abstract]  Here, we present a simple and rapid protocol to measure the extent of cell-to-cell movement of RNA viruses in planta. To do that, the green fluorescent protein (GFP) gene was incorporated into the genome of Melon necrotic spot virus (MNSV) as a coat protein (CP) fusion protein using the Thosea asigna virus 2A catalytic peptide (TaV 2a) (Serra-Soriano et al., 2014). TaV 2a allows the co-translational cleavage of the fusion protein resulting in the independent ...
