catalytic subunit

基本解释

The typical CDK catalytic subunit contains a 300 amino acid catalytic core that is completely inactive when monomeric and unphosphorylated.
典型的CDK催化亚基包含300个氨基酸催化核心，而当CDK独立存在和非磷酸化时是完全没有活性的。
More than 30% of various solid tumor types were recently found to have mutations in PIK3CA, the catalytic subunit of PI3K, and the PI3K signaling pathway is deregulated by a variety of mechanisms.
研究发现约30%的人类实体瘤存在PIK3CA基因的突变，导致PI3K信号途径在不同水平发生调控异常。
