摘要：

1. 1. An amine oxidase (MSAO) and a ceruloplasmin (MSC) have been purified to homogeneity from Mugil cephalus serum. 2. 2. Gel chromatography and SDS-PAGE indicate that MSAO may be a dimer (Mr 190,000) of identical subunits while MSC is composed of one unit only with a Mr of 118,000. 3. 3. The absorption spectrum of MSAO is similar to other serum amine oxidases and the carbonyl cofactor may be pyrrolo-quinolin quinone. 4. 4. MSC contains 6 copper ions per mole of protein and is a glycoprotein containing about 20% carbohydrate by weight. © 1990.
