PKI PKA Inhibitor (5-24) is a synthetic peptide inhibitor of PKA (cAMP-dependent protein kinase) (Ki= 2.3 nM) derived from the active site of the skeletal muscle inhibitor protein.1It mimics the protein substrate by binding to the catalytic site through the arginine-cluster basic subsite.1The prominent enzyme-substrate interaction site occurs where PKA catalytic subunit residues Tyr235and Phe239form a sandwich-like structure with residue Phe10of PKI (5-24).2
Protein Kinase C (19-31) TFA 是蛋白激酶 C (PKC)的抑制剂,是由 PKCa (残基 19-31) 伪底物调控域衍生而来,25 位丝氨酸取代野生型丙氨酸作为蛋白激酶 C 底物肽,用于检测蛋白激酶 C 的活性。Protein kinase C (PKC) TFA 通过磷酸化丝氨酸和苏氨酸氨基酸残基上的羟基来调控其它蛋白的功能。
Protein Kinase C (19-31) TFA, a peptide inhibitor of protein kinase C (PKC), derived from the pseudo-substrate regulatory domain of PKCa (residues 19-31) with a serine at position 25 replacing the wild-type alanine, is used as protein kinase C substrate p
