Chemical and immunological properties of B. anthracis arginase and its metabolic involvement.

An arginase isolated from a capsulated Bacillus anthracis strain was highly purified and crystallized. The chemical and immunological characteristics of this enzyme re described. Some very important properties differ from those of another bacterial arginase, i.

Interaction of alpha 2-macroglobulin with L-asparaginase.

Obvious protection of the catalytic activity of Esch. coli L-asparaginase by alpha 2-macroglobulin (alpha 2M) was observed under conditions otherwise propitious to the dissociation of the tetrameric molecule into inactive subunits, i.e.
