Malantide is a synthetic dodecapeptide derived from the site phosphorylated by cAMP-dependent protein kinase (PKA) on the β-subunit of phosphorylase kinase. Malantide is a highly specific substrate for PKA with a K m of 15 μM and shows protein inhibitor (PKI) inhibition >90% substrate phosphorylation in various rat tissue extracts. Malantide is also an efficient substrate for PKC with a K m of 16 μM.

体外研究(In Vitro)
The Km values of Malantide are 15 μM and 223 μM for PKA and PKG, respectively. The Vmax values are 23.8 units/mg and 6.6 units/mg for for PKA and PKG, respectively.A statistically significant effect of isoprenaline on the activity ratio of guinea-pig heart was only: observed with Malantide. has not independently confirmed the accuracy of these methods. They are for reference only.
