Amino acid sequence of a region on the glycogen-binding subunit of protein phosphatase-1 phosphorylated by cyclic AMP-dependent protein kinase

The amino acid sequence of a region on the glycogen-binding (G)-subunit of protein phosphatase-1G that is phosphorylated by cyclic AMP-dependent protein kinase has been determined. The sequence is: (formula see text) This finding will facilitate studies of the effects of hormones on the phosphorylation state of the G-subunit in vivo.
