Uninfected roots of yellow lupin contain an abundant 18 kDa protein (referred to as R18), absent in the mature nodules. Some properties of this polypeptide are apparently similar to those of lupin leghemoglobins. However, the lack of any immuno crossreaction between R18 and leghemoglobin and differences in N-terminal amino acid sequences indicate that these proteins are coded by different genes. The decrease in the content of R18 protein in developing nodule is associated with the increased synthesis of leghemoglobin. This implies coordination of both events.
未感染的黄羽扇豆根含有丰富的18 kDa蛋白质(称为R18),成熟根瘤中不存在这种蛋白质。该多肽的一些特性显然与羽扇豆豆血红蛋白的特性相似。然而,R18与豆血红蛋白之间缺乏任何免疫交叉反应以及N端氨基酸序列的差异表明这些蛋白质由不同的基因编码。发育中的根瘤中R18蛋白含量的减少与豆血红蛋白合成的增加相关。这意味着这两个事件是协调的。
