产品介绍 | H1-7(组蛋白H1磷酸化位点),PKA底物是一种合成的肽,可作为PKA(依赖cAMP的蛋白激酶)的假底物。该肽源于小牛胸腺组蛋白H1丝氨酸38的氨基酸序列,用于研究PKA催化亚基的反应机理。H1-7的磷酸化绝对催化速率比H1大,比整个组蛋白H1的绝对米氏常数大40倍,但亲和力较低。H1-7的肽序列:RRKASGP。 CAS:65189-70-0(free basis) H1-7 (histone H1 phosphorylation site), PKA Substrate is a synthetic peptide that acts as a pseudo substrate for PKA (cAMP-dependent protein kinase). This peptide was derived from the calf thymus histone H1 amino acid sequence about serine-38 and was used to research the reaction mechanism of the PKA catalytic subunit. H1-7 exhibits a greater absolute catalytic rate of phosphorylation than H1, an absolute Michaelis constant 40-fold greater than whole histone H1, but exhibits less affinity. Peptide sequence of H1-7: RRKASGP. |
