Transient kinetics of copper-containing lentil (Lens culinaris) seedling amine oxidase.

The reaction between lentil (Lens culinaris) seedling amine oxidase and its chromogenic substrate, p-dimethylaminomethylbenzylamine, has been studied by the stopped-flow technique. Upon being mixed with substrate in the absence of oxygen, the enzyme is bleached in a complex kinetic process. A yellow intermediate absorbing at 464 nm and the first product (aldehyde) are formed in subsequent steps...

Kinetics of Adaptation to Osmotic Stress in Lentil (Lens culinaris Med.) Roots.

When intact roots of lentil (Lens culinaris Med.) are subjected to severe osmotic stress by treatment with a solution of low water potential, they immediately begin to shrink. Within 10 to 15 minutes, shrinkage ceases, and within 20 minutes, the roots resume growth. The time lag between application of osmoticum and resumption of growth varies from about 10 to 30 minutes over the range of extern...

Indirect in vitro regeneration of lentil (Lens culinaris Medik.)

Establishment of an efficient and reproducible regeneration protocol is one of the basic prerequisites for genetic transformation of any crop plant. In vitro culture of lentil has proven to be difficult. In spite of a number of reports on the regeneration of this plant, very few satisfying and reproducible protocol has yet been reported. This study carried out for investigation of diff...

Direct in vitro regeneration of lentil (Lens culinaris Medik.).

This study surveyed a rapid, efficient and reproducible protocol for in vitro shoot regeneration and rooting by different explants and different concentration of BAP. Due to optimization of shoot regeneration, two media including of MS and modified MS (MS salts with double concentration of CaC21, and B5 vitamins), different explants such as decapitated embryo axes, epicotyls and cotyledonary no...

Conformational lock and dissociative thermal inactivation of lentil seedling amine oxidase.

The kinetics of thermal inactivation of copper-containing amine oxidase from lentil seedlings were studied in a 100 mM potassium phosphate buffer, pH 7, using putrescine as the substrate. The temperature range was between 47-60 degrees C. The thermal inactivation curves were not linear at 52 and 57 degrees C; three linear phases were shown. The first phase gave some information about the number...
