Whole leaves and guard-cell protoplasts of the C 3 plant Vicia faba L. (broad bean) were separately extracted following a period of illumination or following a period of darkness. Kinetic parameters of phosphoenolpyruvate carboxylase (PEPC, EC 4.1.1.31), V~a x and K~Ep.~g ~, were determined as a fun
## Abstract The properties of a Ξ²βgalactosidase from a thermophilic Bacillus have been studied and compared with the properties of the enzyme contained in whole cells and in cells entrapped in a polyacrylamide gel matrix. The partially purified enzyme appears to be optimally active at a temperature
