Abstract
Induced-transport tests with comparatively undegraded rabbit liver phosphoglucomutase show that the enzyme possesses a phosphoenzyme mechanism and that any interconversion of phosphoenzyme forms is very rapid. A relatively stable 32P-labelled phosphoenzyme was isolated, which exchanged label rapidly with substrates. The phospho group appears to be bonded to a serine residue on the enzyme.
