||"To determine the kinetic parameters of p38a kinase activity,
[researchers] selected a synthetic peptide derived from the EGF receptor
(residues 661–681 EGFR peptide) and the transcription factor
ATF2?109 (residues 1–109) as p38a substrates...
All steady-state kinetic studies were performed at pH 7.0 and
||"By fitting the Michaelis-Menten equation to the experimental
data, the values of kcat and Km were determined to be
31.6±1.1 s^-1 and 656±62µM, respectively."
