Markedly different ascorbate dependencies of the sequential alpha-ketoglutarate dioxygenase reactions catalyzed by an essentially homogeneous thymine 7-hydroxylase from Rhodotorula glutinis.
The alpha-ketoglutarate dioxygenase, thymine 7-hydroxylase (EC, has been purified from cultures of Rhodotorula glutinis grown with thymine as a nitrogen source. The purification schemeExpand

Experimental and theoretical evidence supporting the role of Gly363 in blood coagulation factor IXa (Gly193 in chymotrypsin) for proper activation of the proenzyme.
Factor IX is the zymogen of the serine protease factor IXa involved in blood coagulation. In addition to a catalytic domain homologous to the chymotrypsin family, it has Ca2+, phospholipid, andExpand

Characterization of three abnormal factor IX variants (Bm Lake Elsinore, Long Beach, and Los Angeles) of hemophilia-B. Evidence for defects affecting the latent catalytic site.
Abnormal factor IX variant proteins were isolated from the plasmas of three unrelated severe hemophilia-B families that had been previously shown to contain functionally impaired moleculesExpand

Intrinsic versus extrinsic coagulation. Kinetic considerations.
A study to compare the kinetics of activation of factor IX by Factor XIa/Ca2+ and by Factor VIIa/tissue factor/Ca2+ has been undertaken. When purified human proteins, detergent-extracted brain tissueExpand

Stoichiometry of binding of high molecular weight kininogen to factor XI/XIa.
Factor XI is a dimeric protein and circulates in plasma complexed with high molecular weight kininogen (HMWK). We investigated the binding of HMWK to factor XIa utilizing two active site directedExpand
