Summary

A new type of enzyme, modulator-dependent protein kinase (type I) (M-PKI), was successfully isolated from the cytosol fraction of mouse testes. It was eluted slightly after the peak of cyclic GMP-dependent protein kinase (G-PK) by Sephadex G-200 gel filtration. Unlike either cyclic AMP-dependent protein Kinase (A-PK) or G-PK, its maximal activity depended exclusively on the presence of crude protein kinase modulators (PKM) or partially purified stimulatory modulator (PKMs).
