Metabolic pathways of aerobic bacteria able to assimilate sulfur can provide biocatalysts for biodesulfurization of petroleum and of other sulfur-containing pollutants. Of major interest is the so-called “4S pathway,” in that C–S bonds are specifically cleaved leaving the carbon skeleton of substrates intact. This pathway is carried out by four enzymes, named Dsz A, B, C, and D. In view of a possible...
The cyclin-dependent kinase inhibitor Sic1 is an intrinsically disordered protein (IDP) involved in cell–cycle regulation in the yeast Saccharomyces cerevisiae. Notwithstanding many studies on its biological function, structural characterization has been attempted only recently, fostering the development of production and purification protocols suitable to yield large amounts of this weakly expressed...
