carboxylate

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 運用cpdna基因組編碼的磷酸核酮糖羧化酶大亞基( rbcl )的基因序列測定而構建的系統樹,顯示蹄蓋蕨科、金星蕨科、烏毛蕨科以及其他科構成一條與鱗毛蕨科平行的分支,因此可以說明kramer & kato ( 1990 )把蹄蓋蕨科放入廣義的鱗毛蕨科是不合理的。

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 在葉肉細胞的葉綠體中二氧化碳與磷酸烯醇丙酮酸結合形成草酰乙酸,后被運到鄰近的維管束鞘細胞,在那里二氧化碳被釋放,后被核酮糖二磷酸羧化酶固定形成3磷酸甘油酸,這是卡爾文的循環第一步。

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,在卡爾文循環中是二氧化碳固定的第一步。
