The alpha subunit of the F(1)-ATPase complex of maize is a mitochondrial translational product, presumably encoded by the mitochondrial genome. Based on nucleotide and amino acid homology, we have identified a mitochondrial gene, designated atpalpha, that appears to code for the F(1)-ATPase alpha subunit of Zea mays. The atpalpha gene is present as a single copy in the maize. Texas cytoplasm and is actively transcribed. The maize alpha polypeptide has a predicted length of 508 amino acids and a molecular mass of 55,187 daltons. Amino acid homologies between the maize mitochondrial alpha subunit and the tobacco chloroplast CF(1) and Escherichia coli alpha subunits are 54 and 51%, respectively. The origin of the atpalpha gene is discussed.
玉米 F(1)-ATP 酶复合α亚基是一种线粒体翻译产物，推测由线粒体基因组编码。基于核苷酸和氨基酸同源性，我们鉴定了一个线粒体基因，命名为 atpalpha，它似乎编码玉米的 F(1)-ATP 酶α亚基。atpalpha 基因在玉米德克萨斯细胞质中作为单拷贝存在，并被转录。玉米α多肽的预测长度为 508 个氨基酸，分子量为 55187 道尔顿。玉米线粒体α亚基与烟草叶绿体 CF(1)和大肠杆菌α亚基的氨基酸同源性分别为 54%和 51%。还讨论了 atpalpha 基因的起源。
