Carboxylase an enzyme that catalyzes the incorporation of carbon dioxide into a substrate molecule 羧化酶：一类催化二氧化碳合成底物分子的酶。

The most important carboxylase in plants is ribulose bishosphate carboxylase ( rubisco ) , which catalyzes the carboxyation of ribulose bisphosphate , the ‘ carbon - fixing ’ first step in the calvin cycle 在植物中最重要的羧化酶是核酮糖二磷酸羧化酶，它可以羧化核酮糖二磷酸，在卡尔文循环中是二氧化碳固定的第一步。

In these chloroplasts carbon dioxide combines with phosphoenolpyruvate to form oxaloacetic acid , which is transported to the bundle sheath cells , where the carbon dioxide is released , then fixed by the enzyme ribulose bisphosphate carboxylase to form glycerate 3 - phosphate , the first step in the calvin cycle 在叶肉细胞的叶绿体中二氧化碳与磷酸烯醇丙酮酸结合形成草酰乙酸，后被运到邻近的维管束鞘细胞，在那里二氧化碳被释放，后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸，这是卡尔文的循环第一步。

Based on recent molecular phylogenetic analyses using nucleotide sequences of the encoding the large subunit of ribulose 1 , 5 - bisphyosphate carboxylase / oxygenase ( rbcl ) , hypodematium should be not included in the athyriaceae , it has closely related to dryopteridaceae . on the other hand , athyriaceae , thelypteridaceae , blechnaceae , onocleaceae and woodisaceae form a large clade , so it may explain that tryon & tryon ( 1982 ) and kramer & kato ( 1990 ) putting it forward as dryopteriaceae s . 1 运用cpdna基因组编码的磷酸核酮糖羧化酶大亚基( rbcl )的基因序列测定而构建的系统树，显示蹄盖蕨科、金星蕨科、乌毛蕨科以及其他科构成一条与鳞毛蕨科平行的分支，因此可以说明kramer & kato ( 1990 )把蹄盖蕨科放入广义的鳞毛蕨科是不合理的。

Elevated [ co2 ] treatment resulted in the larger accumulation of carbohydrate ( soluble sugar and starch ) in leaves of anthurium andraeanum lind during short - term experiment , but the difference of three treatment groups is no striking during long - term experiment . chlorophyll content , chlorophyll a / chlorophyll b ratio in leaves increased , while soluble protein decreased in elevated [ co2 ] during experiments . elevated [ co2 ] led to the increase of rubp carboxylase activity and the decline of glycolic acid oxidase activity during short - term experiment , but the rubp carboxylase activity decreased after 60 d , the glycolic acid oxidase activity increased after 90 d 高浓度co _ 2处理的红掌，叶片中的叶绿素含量增加，叶绿素a叶绿素b升高，但可溶性蛋白含量下降，并且随着处理时间的延长，可溶性蛋白含量的下降更为明显，处理150d时， t1 、 t2的可溶性蛋白含量与ck相比分别下降了36 . 7 、 28 . 2 ；高浓度co :处理的前30d ，高浓度c02抑制了go活性， rubpc活性升高:处理以记时，高浓度coz处理组的rubpc活性降低， go活性仍然低于对照;处理以月后，高浓度co :处理组的rubpc活性低于对照，其中t2的rubpc活性显著下降，而go活性升高。
