THE CALCIUM BINDING SITES OF THE BAKERS' YEAST TRANSKETOLASE
The calcium binding sites of Bakers' Yeast Transketolase (TK) was elucidated by estimating the pKa values of the functional groups that bind to calcium. These pKa's were found to be 6.25 and 7.2 relating to the pKa's of the two immidazol moieties of histidine residues on the enzyme. The rate of the binding of calcium to the enzyme was obtained separately as a function of pH. Maximum values ...
متن کاملBinding Globulin by Analogues of Hydantoin
Administration of the anticonvulsant 5,5-diphenylhydantoin sodium (DPH, Dilantin) depresses the level of serum protein-bound iodine (PBI) without inducing clinical hypothyroidism or changing other measures of thyroid function, such as 24-hour thyroidal accumulation of I131, thyroidal clearance of I131, serum cholesterol, and basal metabolic rate (1). Since DPH also induces a fall in the serum P...
متن کاملPrediction of the water content in protein binding sites.
An efficient molecular simulation methodology has been developed to determine the positioning of water molecules in the binding site of a protein or protein-ligand complex. Occupancies and absolute binding free energies of water molecules are computed using a statistical thermodynamics approach. The methodology, referred to as Just Add Water Molecules (JAWS), features "theta-water" molecules th...

متن کاملStudies of In-Vitro Amlodipine and Arsenic Displacement Interaction at Binding Sites of Bovine Serum Albumin
In this study, the binding of amlodipine (a Ca ++ channel Blocker) and arsenic (metalloid) to bovine serum albumin (BSA) was studied by equilibrium dialysis(ED) method in order to have an insight into their binding chemistry to BSA. Free amlodipine concentration was increased due to addition of arsenic which reduced the binding of the compounds to BSA. However, the free fraction was not increa...
