摘要：

Isocitrate lyase was partially purified from germinating spores of the fern Anemia phyllitidis. The enzyme requires Mg2+ and thiol compounds for maximal activity and has a pH optimum between 6.5 and 7.5. The Km of the enzyme for threo-Δs-isocitrate is 0.5 mM. Succinate inhibits the enzyme non-competitively (Ki. 1.8 mM). The increase of isocitrate lyase activity is closely correlated with the induction of the germination process. The fall of enzyme activity during germination is associated with the decline in triglyceride reserves. © 1979.
