Ferredoxin was isolated from individual Leucaena glauca trees, and the distribution of amino acids at three of the four sites of sequence heterogeneity was determined. The results indicated that the most probable causes of the observed microheterogeneity are the presence of either nonallelic nuclear genes or differing chloroplast genes, and also ambiguity in translation of the genetic code.
从个别银合欢树中分离出了铁氧化还原蛋白,并确定了序列异质性四个位点中三个位点的氨基酸分布。结果表明,观察到的微异质性最可能的原因是非等位核基因的存在、叶绿体基因的差异,以及遗传密码翻译中的模糊性。
