Hyperhomocysteinemia and arteriosclerosis: historical perspectives

Early concepts of the origin of arteriosclerosis were introduced in the 19th century by Rokitansky and Virchow, who described mural thrombosis, inflammatory damage to arterial intima, increased intimal permeability to plasma, mucoid degeneration of arterial wall, deposition of plasma lipids in plaques, and fibrosis and calcification of plaques...

Role of methionine residues of albumin in T-R conversion of hemoglobin

Background: Hemoglobin (Hb) has peroxidase (POD)-like activity. We found that the addition of albumin to human Hb purified from venous erythrocytes increased its POD-like activity.

Methods: We treated human Hb with a Blue-Toyopearl column of immobilized albumin, compared the treated Hb and native Hb for POD-like activity, the level of Hb-bound 2,3-diphosphoglycerate (2,3-DPG), and the absorption spectrum, and found that treatment with albumin released 2,3-DPG from Hb, resulting in a tense-relaxed (T-R) conversion and increased POD-like activity.

Results: The addition of human, mouse, rat, or bovine albumin to human Hb increased its POD-like activity...

Keywords: Albumin, domain, domain I, hemoglobin, Methionine, POD-like activity

Metabolic regulatory properties of S-adenosylmethionine and S-adenosylhomocysteine

In mammalian liver, two intersecting pathways, remethylation and transsulfuration, compete for homocysteine that has been formed from methionine...

Keywords: adenosylhomocysteine, adenosylmethionine, homocysteine, Methionine, transmethylation, transsulfuration
