Phosphoprotein phosphatase in the central nervous system of Manduca sexta.


The existence and some enzymological properties of phosphoprotein phosphatase (EC have been established in the larval central nervous system of the tobacco hornworm, Manduca sexta (Lepidoptera: Sphingidae). A simple, sensitive and reproducible assay employing 32-P-labeled protamine as a phosphoprotein substrate was employed to measure phosphatase… (More)
