资源简介：
Soil extracellular enzymatic catalysis is the rate-limiting step in soil organic matter decomposition, and <i>V</i><sub><em>max</em></sub> and <i>K</i><sub><em>m</em></sub> are enzyme kinetic parameters reflecting enzyme catalytic capacity. However, it is still far from clear how these enzymatic kinetic parameters respond to altered precipitation and subsequently influence soil microbial respiration (<i>R</i><sub><em>h</em></sub>). Here, we examined the <i>V</i><sub><em>max</em></sub> and <i>K</i><sub><em>m</em></sub> of seven soil hydrolytic enzymes and polyphenol oxidase (PPO), <i>R</i><sub><em>h</em></sub>, and microbial biomass carbon (MBC) under altered precipitation (-30%, ambient, and +30%) across three steppes.
