The review presents data on the location, nature, properties, number, and expression of carbonic anhydrase genes in the photosynthesizing cells of C3 plants. The available data about the presence of carbonic anhydrases in plasma membrane, cytoplasm, mitochondria, chloroplast stroma and thylakoids are scrutinized. Special attention was paid to the presence of carbonic anhydrase activities in the different parts of thylakoids, and on collation of sources of these activities with enzymes encoded by the established genes of carbonic anhydrases. The data are presented to show that the consistent incorporation of carbonic anhydrases belonging to different families of these enzymes forms a coherent system of CO molecules transport from air to chloroplasts in photosynthesizing cells, where they are included in organic molecules in the carboxylation reaction. It is discussed that the manifestation of the activity of a certain carbonic anhydrase depends on environmental conditions and the stage of ontogenesis.
这篇综述展示了关于C3植物光合细胞中碳酸酐酶基因的位置、性质、特性、数量及表达的数据。对质膜、细胞质、线粒体、叶绿体基质和类囊体中碳酸酐酶存在情况的现有数据进行了详细审查。特别关注了类囊体不同部位碳酸酐酶活性的存在情况,以及这些活性的来源与已确定的碳酸酐酶基因所编码的酶的比对。所呈现的数据表明,属于这些酶不同家族的碳酸酐酶的一致整合形成了一个连贯的系统,用于将CO分子从空气转运到光合细胞的叶绿体中,在羧化反应中CO分子被纳入有机分子。文中讨论了特定碳酸酐酶活性的表现取决于环境条件和个体发育阶段。
