Transferrin (Tf) is the major iron-transporting protein in the human body and, for this reason, has been extensively studied in biomedicine. This protein undergoes a complex glycosylation process leading to several glycoforms, some of which are impor

The efficient enzyme-catalyzed coupling of the indolic alkaloids catharanthine and vindoline was carried out by exploiting the oxidoreductases laccases and atmospheric oxygen. Following NaBH4 reduction of the eniminium cationic intermediate, the synt

The relative ratio of the dimers obtained by laccase-catalyzed oxidation of tetrahydronaphthyl derivatives was profoundly influenced by the nature of the organic solvent used. For instance, in the oxidation of 5,6,7,8-tetrahydronaphtalen-2-ol (1), th

Laccase-mediated oxidation of the steroid hormone 17β-estradiol 1 in organic solvents or in a biphasic system allowed the isolation of the C–C and C–O dimers 1a–d. Concerning the C–C dimers, the relative ratio of the symmetric 4-4′ 1c and

Laccases from different sources have been used, for the first time, for the selective oxidation of the stilbenic phytoalexin trans-resveratrol (3,5,4′-trihydroxystilbene, 1a) on a preparative scale. Specifically, the enzymes from Myceliophtora ther
