3 Blumenthal, Donald K.Characterization of the regulatory domain of the gamma-subunit of phosphorylase kinase. The two noncontiguous calmodulin-binding subdomains are also autoinhibitory.Phosphorylase kinase is a multimeric protein kinase (alpha 4 beta 4 gamma 4 delta 4) whose enzymatic activity is conferred by its gamma-subunit. A library of 18 overlapping synthetic peptides spanning residues 277-386 of the gamma-subunit has been prepared to use in identifying important regulatory ...Metabolism; Phosphorylase Kinase1995-09-22
4 Blumenthal, Donald K.Gamma-subunit of skeletal muscle phosphorylase kinase contains two noncontiguous domains that act in concert to bind calmodulin.Phosphorylase kinase is a Ca2+-regulated, multisubunit enzyme that contains calmodulin as an integral subunit (termed the delta-subunit). Ca2+-dependent activity of the enzyme is thought to be regulated by direct interaction of the delta-subunit with the catalytic subunit (the gamma-subunit) in the ...Pharmacology; Metabolism; Enzymology1989-10-15
