Regulation of the
asparaginase
activity rhythm in L. michotii has previously been shown to be dependent on a reversible phosphorylation process. Asparaginase was isolated as a purified protein complex having self-
phosphorylating
capacities, which were analyzed. In vivo phosphorylation of
asparaginase
complex was performed synchronously with the rhythm of
asparaginase
activity. In vitro self-phosphorylation of
asparaginase
complex resulted from the activity of an ATP-Mg2+-dependent protein kinase, which phosphorylated protein at threonine residues and was not dependent on cyclic AMP, Ca2+ or calmodulin. Dephosphorylation of this complex was due to a Mg2+-Zn2+-dependent protein phosphatase, molybdate inhibited, the specificity of which, for low-molecular-weight nonprotein phosphoesters, was broad.
