Abstract

S1 and S2 are short linear mitochondrial DNA molecules found in a particular male sterile cytoplasm of maize. We show here that these DNA molecules and two other related linear DNA species found in maize mitochondria, have proteins attached, probably covalently, to their 5' ends. This is the first demonstration of such a linear DNA-terminal protein association in higher eukaryotes. Such proteins may be involved in priming replication of these DNAs.

摘要

S1和S2是在玉米特定雄性不育细胞质中发现的短线性线粒体DNA分子。我们在此表明，这些DNA分子以及在玉米线粒体中发现的其他两种相关线性DNA种类，在其5'端附着有蛋白质，可能是共价附着。这是高等真核生物中这种线性DNA-末端蛋白质关联的首次证明。此类蛋白质可能参与这些DNA的复制起始。
