摘要:
利用NCBI数据库及电子克隆技术克隆了水稻PLA-I{gamma}1类似基因,命名为OsPLA-I{gamma}1。序列分析表明,其开放阅读框为1 374 bp,只含有1个外显子,没有内含子。利用生物信息学软件对OsPLA-I{gamma}1蛋白的理化性质、疏水性/亲水性、跨膜区、亚细胞定位、蛋白质结构及功能等进行预测分析。结果表明:该蛋白分子式为C2138H3409N625O637S19,氨基酸总数为457个,分子量为48 670.5,理论等电点为pI 8.86,为亲水性稳定蛋白;α螺旋和不规则卷曲是其蛋白质二级结构的主要构件,延伸链散布于整个蛋白质中;属于脂肪酶,活性受可逆磷酸化或糖基化作用调控,具有能量代谢功能,是水稻的生长因子;定位于叶绿体基质腔中;含有19个蛋白激酶磷酸化位点,“Ser”磷酸化位点11个,“Thr”磷酸化位点5个,“Tyr”磷酸化位点3个;含有17个“O-β-GlcNAc”位点,丝氨酸5个,苏氨酸12个;与粗山羊草、蒺藜苜蓿、甘蓝型油菜、拟南芥的脂肪酶有较高的同源性。本研究结果为进一步研究该基因的功能和作用机制奠定基础。
