[The serine- and threonine dehydratases of brucellae].
In studying 62 strains of brucellae of all the known species an inductive enzyme--1-serine-hydrolyase(desaminating) was revealed in the intact cells and cell-free extracts. The activity of this enzyme depended on the species of brucellae and showed a sharp elevation in destruction of the cells with supersonic waves. Intact brucellae failed to desaminate treonine. A constitution enzyme 1-treonine-hydrolase (desaminating) was found in the cell-free extracts of Br. neotomae and brucellae isolated from murine rodents of the Northern Caucasus. Some properties of both enzymes were studied.
