Characterisation of cyclin D1 down-regulation in coronavirus infected cells.

abstract：:Protein deglutathionylation is mainly catalyzed by glutaredoxins (GRXs). We have analyzed the biochemical properties of four of the six different GRXs of Chlamydomonas reinhardtii. Kinetic parameters were determined for disulfide and dehydroascorbate reduction but also for deglutathionylation of artificial and protein...
