Establishing the protein posttranslational modification (PTM) landscape at the proteome scale relies on the target specificity of the relevant enzyme catalysts. Su et al. [ ACS Catal. 2021, 11, 14877] proposed that “the kcat/Km value is not the best parameter to determine the in vivo substrate specificity of an enzyme. Instead, the binding affinities of substrates are more important for determining
