1-氨基環丙烷-1-甲酸
化合物
1-氨基環丙烷-1-甲酸,簡稱ACC,是一種雙取代的環狀α-胺基酸,其中環丙烷環與胺基酸的Cα原子稠合。它是一種白色固體。目前已知有許多種環丙烷取代的胺基酸,但這種是天然存在的。[2]與甘氨酸一樣,但與大多數α-胺基酸不同,ACC不是手性的。

生物化學
ACC是植物激素乙烯的前體。[3][4]它由ACC合酶(EC 4.4.1.14)從甲硫氨酸合成,並通過ACC氧化酶(EC 1.14.17.4)轉化為乙烯。[5]
ACC還表現出不依賴於乙烯的信號傳導,該信號通過激活類似於人類和動物神經系統反應所涉及的蛋白質,在授粉和種子生產中發揮關鍵作用。更具體地說,ACC信號促進花粉管趨化因子LURE1.2在胚珠孢子體組織中的分泌,從而增強花粉管的吸引力。此外,ACC通過根原生質體中的穀氨酸受體樣通道激活含Ca2+的離子流。[6]
ACC可被土壤微生物(細菌和真菌)用作氮和碳的來源。[7]因此,已證明使用ACC培養土壤可誘導編碼ACC脫氨作用的基因豐度,這可能對植物生長和脅迫耐受性產生積極影響。[7][8]
