Sequence from site of phosphorylation by PKA on the ß-subunit of phosphorylase kinase. Highly specific and very potent substrate for cAMP-dependent protein kinase (PKA). PKI inhibited 90% substrate phosphorylation in various tissue extracts. Km=15 µM for PKA; 223 µM for PKG. Useful in measuring activity of this PKA via phosphorylation-induced decrease in fluorescence. Product Specification Sequence:H-Arg-Thr-Lys-Arg-Ser-Gly-Ser-Val-Tyr-Glu-Pro-Leu-Lys-Ile-OH MW:1633.8 CAS:86555-35-3 Formulation:Lyophilized. Purity:≥95% (HPLC) Solubility:Soluble in water. Long Term Storage:-20°C
