Biochemical, physicochemical and molecular characterization of a genuine 2-Cys-peroxiredoxin purified from cowpea [Vigna unguiculata (L.) Walpers] leaves

► A 2-Cys-Prx (Vu-2-Cys-Prx) was purified from cowpea (Vigna unguiculata) leaves. ► Vu-2-Cys-Prx binds to chitin, is a 44/46 kDa protein with pI of 4.56 - 4.72. ► Its Cys52, Pro45, Thr49, and Arg128 residues are conserved as in all other 2-Cys-Prx. ► Vu-2-Cys-Prx prevented DNA degradation, forms decamers, and has chaperone activity.
