%A Liu Xiong and Yan Long-fei %T Comparative Study on Interaction of DNaseⅠ with Pollen Actin and Rabbit Muscle Actin %0 Journal Article %D 1995 %J J Integr Plant Biol %R %P -${article.jieShuYe} %V 37 %N 3 %U {https://www.jipb.net/CN/abstract/article_23736.shtml} %8 %X Actin purified from maize pollen grains like actin from other sources could considerably inhibit the activity of DNase Ⅰ . A linear relationship existed between inhibition and the concentration of actin. However, DNase Ⅰ was less inhibited by pollen actin than by rabbit muscle actin under the same conditions. The values of Kapp of inhibition were 1.25 μg/mL for pollen actin and 0.75 μg/mL for rabbit muscle actin. DNase Ⅰdepolymerized both pollen and rabbit muscle actin filaments. But the rate of depolymerization of pollen F-actin was higher than that of rabbit muscle F-actin under the same conditions.
