Abstract The inactivation by x-rays of monomolecular layers of catalase and of bovine serum albumin (BSA) in pure air-free water has been studied. No measurable inactivation can be detected with doses of less than about 100,000 r. With doses of 500,000 r. the respective inactiyations are 48 and 12%. The ionic yields for catalase and BSA in solution have also been measured and the values obtained are 0.044 and 0.023 molecules/ion pair, respectively. From these measurements, the half-life time of… Expand

The kinetics suggest that only one in 9.3 free radicals which react with one enzyme molecule is effective in causing loss of enzymatic activity, which is of the first order rather than the second order. Expand
Monolayer technique to study effects of lonizing radiations on histone.
It was concluded that irradiation produces a degree of fragmentation and some modifications in the histone molecules, which cause hycrophlilic groups to go into the aqueous under phase and results in lowering of the residual charges carried by the molecules in the monolayer. Expand
Irradiation effects on enzymes (in vitro)
Enzymes are the essential catalysts of the breakdown and synthesis of vital constituents in cells of living organisms and usually display a high degree of specificity. Without enzymes the cells couldExpand

The inactivation of an enzyme (carboxypeptidase) by X- and α-radiation
The inactivation of aqueous solutions of pure crystalline carboxypeptidase by X-radiation and α-radiation has been studied. It is concluded that in each case the enzyme molecules are inactivated byExpand
Direct and indirect actions of radiation on viruses and enzymes
It is found that the inactivation dose is independent of concentration at high concentrations, and at low concentrations also attains a constant, but lower, value. Expand

It is shown that the inactivation of such layers of bovine serum albumin with deuterons is logarithmic, indicating that the majority of the serologically active units are of the same size. Expand

Evidence for the existence of at least two forms of stable catalase has been presented and data are shown to indicate two possible alternative molecular weights (about 250,000 and 130,000) forCatalase. Expand
