Abstract

Abstract A diamine oxidase (DAO)(EC 1.4. 3.6) has been purified to homogeneity from lentil seedlings. The purified protein has a MW of 154 000 and is composed of two apparently identical subunits. It contains two CU 2+ atoms and one carbonyl-like group per mol. The purified enzyme is pink-red in concentrated solution and shows a broad, well-defined, absorption band in the visible region centered at 498 nm. The ESR spectrum is typical of ...
