摘要

荧光标记脂质结合实验表明,CaMBP-10具有典型的非特异性脂质转移蛋白(nsLTP)的脂质结合特征。我们比较了钙调素(CaM)对CaMBP-10和玉米nsLTP脂质结合活性的影响。在Ca(2+)或EGTA的存在下发现了不同的影响。W-7和TFP可以消除CaM的影响。因此,CaM可以与CaMBP-10和玉米nsLTP特异性相互作用。CaMBP-10与玉米nsLTP之间可能存在不同的CaM调控机制。

[The effects of calmodulin on the lipid-binding activity of CaM-binding protein-10 and maize non-specific lipid transfer protein].

Fluorescence-marked lipid binding experiment shows that CaMBP-10 has typical lipid binding feature of non-specific lipid transfer protein (nsLTP). We have compared the effects of calmodulin (CaM) on the lipid-binding activity of CaMBP-10 and maize nsLTP. Different influences were found in the presence of either Ca(2+) or EGTA. W-7 and TFP could abolish the influence of CaM. Therefore, it is suggested that CaM could interact specifically with both CaMBP-10 and maize nsLTP. Probably, there are different CaM regulatory mechanisms between CaMBP-10 and maize nsLTP.
