Abstract:
:The influence of several commercial albumin preparations on the ferroxidase activity of ceruloplasmin (ferroxidase I, ferrous: O2 oxidoreductase EC 1.16.3.1) at pH 6.0 was determined using ferric-transferrin formation. The ability of several albumin preparations to inhibit the ferroxidase activity of ceruloplasmin differs more than three hundredfold. It appears to depend on the method of isolation of albumin rather than the source of albumin, suggesting the existence of an inhibitor bound to albumin. The inhibitor was isolated after chromatography of an albumin preparation on Sephadex G-200. It was identified as citrate by thin layer chromatography and by comparison of the spectrum of the sulfide-pentabromoacetone derivative. Albumin preparations, even with bound citrate, do not exert a significant inhibitory effect at pH 7.4.
